joschim bought a pair of shoes for $40, which was a 20% discount. what was the original price of the shoes?
select one:
a. $8
b. $100
c. $50
d. $45

Explanation:

Step1: Calculate over-limit texts

$2100 - 1000 = 1100$

Step2: Calculate over-limit text cost

$1100 \times 0.15 = 165$

Step3: Calculate total phone bill

$79 + 165 = 244$

Step4: Define discounted price formula

Let original price = $P$. Discounted price: $P \times (1 - 0.20) = 40$

Step5: Solve for original price

$P = \frac{40}{0.80} = 50$

Answer:

1. b. $244
2. c. $50
