Explanation:

Step1: Calculate cost for Airline A

Lilly checks a bag (round - trip, so 2 ways) and doesn't use Wi - Fi or eat a meal.
Flight cost: $214, Baggage fee: $20×2 = $40, Service charge: $25, Wi - Fi and meal: $0.
Total cost: $214 + $40 + $25 = $279? Wait, no, wait. Wait, round - trip flight, baggage fee is per bag each way. So for a round - trip, it's going and coming back, so 2 ways. So baggage fee: 20×2 (since each way, so two ways for the bag). Service charge: 25. Flight: 214. Wi - Fi and meal: 0. Wait, maybe I miscalculated earlier. Wait, let's re - do:

Airline A:
Flight: $214
Baggage: $20 per bag each way. Since it's a round - trip, she has to pay for going and coming back, so 2×$20 = $40
Service charge: $25
Wi - Fi: $0 (she doesn't use)
Meal: $0 (she doesn't eat)
Total: 214+40 + 25=279? Wait, but the option for Airline A is $234. Oh, wait, maybe I misread the baggage fee. Wait, "baggage fee: $20/bag each way" – maybe "each way" means per direction, but for a round - trip, it's two directions. Wait, no, maybe the problem is that she is checking a bag, so for the round - trip, it's one bag going and one bag coming? No, it's one bag, so each way (going and returning) she has to pay $20 per bag. So for one bag, round - trip, it's 2×20 = 40. But the first option says Airline A costs $234. Wait, maybe I made a mistake. Let's check the options. Wait, maybe the service charge is different? Wait, no, let's check each airline:

Wait, maybe the question is that she is flying from Kansas City to San Diego (one - way? No, it's round - trip). Wait, no, the table says round - trip flight. Wait, maybe the baggage fee is per bag each way, but for a round - trip, it's two ways, but maybe the problem is that she checks one bag, so for the round - trip, it's $20×2 (going and coming) = $40. Service charge: $25. Flight: $214. So 214+40 + 25 = 279. But that's not matching the first option. Wait, maybe I misread the service charge. Wait, no, let's check Airline B:

Airline B:
Flight: $235
Baggage: $10 per bag each way, so round - trip: 10×2 = $20
Service charge: $10
Wi - Fi: $0, Meal: $0
Total: 235+20 + 10=265? Wait, no, the fourth option says Airline B costs $265. Wait, let's check Airline C:

Airline C:
Flight: $280
Baggage: one free each way, so $0
Service charge: none
Wi - Fi: free, Meal: $0
Total: $280

Wait, now let's recalculate each airline correctly:

Airline A:
- Round - trip flight: $214
- Baggage fee: $20 per bag each way. Since it's a round - trip, she has to pay for the bag going and coming back. So 2×$20 = $40
- Service charge: $25
- Wi - Fi: $0 (not using)
- Meal: $0 (not eating)
Total for A: 214 + 40+25 = 279

Airline B:
- Round - trip flight: $235
- Baggage fee: $10 per bag each way. Round - trip: 2×$10 = $20
- Service charge: $10
- Wi - Fi: $0
- Meal: $0
Total for B: 235+20 + 10=265

Airline C:
- Round - trip flight: $280
- Baggage fee: one free each way, so $0
- Service charge: none
- Wi - Fi: free, Meal: $0
Total for C: 280

Wait, but the options:

First option: Airline A, $234 – that doesn't match 279. Wait, maybe I misread the baggage fee. Wait, "baggage fee: $20/bag each way" – maybe "each way" is per flight segment, but for a round - trip, there are two segments (going and returning). But maybe the problem is that she is checking a bag, so for the round - trip, it's $20 (one way) + $20 (return way) = $40. But the first option says $234. Wait, maybe the service charge is not applicable? No, the table says service charge: $25 for A. Wait, maybe the question is that she is flying one - way? No, the table says round - trip flight. Wait, maybe I made a mistake in the number of baggage fees. Wait, maybe "each way" means per trip, not per direction. No, "each way" means each direction. Wait, let's check the first option again. The first option says Airline A costs $234. Let's calculate 214 (flight) + 20 (baggage one way) + 25 (service) = 259? No. Wait, maybe the baggage fee is per bag per trip (round - trip), not each way. So $20 per bag for round - trip. Then 214+20 + 25 = 259. Still not 234. Wait, maybe the service charge is $25, but maybe the Wi - Fi and meal are included? No, she doesn't use them. Wait, maybe the problem is that the baggage fee is $20 per bag, but for a round - trip, it's only one way? No, that doesn't make sense. Wait, let's check the options again. The fourth option is Airline B, $265. Let's recalculate Airline B:

Flight: 235, Baggage: 10×2 = 20, Service charge: 10, Total: 235+20 + 10 = 265. That matches the fourth option? Wait, no, the fourth option says "Airline B is the better deal, and it costs $265". Let's check Airline A again. Wait, maybe I misread the baggage fee. Wait, "baggage fee: $20/bag each way" – maybe "each way" is per passenger, no. Wait, maybe the problem is that she is checking a bag, so for the round - trip, it's $20 (for the bag) and the service charge is $25, flight is $214. 214+20 + 25 = 259. No. Wait, maybe the Wi - Fi and meal are subtracted? No, she doesn't use them, so they are $0. Wait, maybe the question is that the baggage fee is $20 per bag, but for a round - trip, it's one way. So 214+20 + 25 = 259. Airline B: 235+10 + 10=255? No, 235+10 (baggage one way) + 10 (service) = 255. No. Wait, I think I made a mistake in the number of baggage fees. Wait, the problem says "check a bag" – so one bag. For a round - trip, she has to pay the baggage fee for going and coming back, so two times. So Airline A: 214 (flight) + 20×2 (baggage) + 25 (service) = 214+40 + 25 = 279. Airline B: 235+10×2 (baggage) + 10 (service) = 235+20 + 10 = 265. Airline C: 280+0 + 0 = 280. So among these, Airline B has the lowest cost of $265. So the fourth option is correct.

Step2: Calculate cost for Airline B

Flight: $235, Baggage: $10×2 = $20 (round - trip, two ways), Service charge: $10, Wi - Fi and meal: $0.
Total: 235+20 + 10 = $265

Step3: Calculate cost for Airline C

Flight: $280, Baggage: $0 (one free each way), Service charge: $0, Wi - Fi and meal: $0.
Total: $280

Step4: Compare costs

Airline A: $279, Airline B: $265, Airline C: $280. So Airline B has the lowest cost of $265.

Answer:

Airline B is the better deal, and it costs $265.
