Question

katie took a plane to visit her grandparents for the summer. at the airport, she paid to check 3 bags. since all of her bags were over the weight limit, she had to pay an additional $6 fee for each bag. katie paid a total of $102 to check her bags. which equation can you use to find the amount of money, x, it costs to check a bag thats under the weight limit? 3x + 6 = 102 6(x + 3) = 102 3(x + 6) = 102 6x + 3 = 102

Explanation:

Step1: Define cost per bag

Let $x$ = base cost for an under-limit bag.

Step2: Cost per over-limit bag

Each over-limit bag costs $x + 6$.

Step3: Total cost for 3 bags

3 bags, total cost = $3(x + 6)$, equals $102$.

Answer:

$3(x + 6) = 102$
