Final answer:
Marsha received $5.03 in change from a $20 bill after buying three pairs of socks, which means she spent a total of $14.97. By dividing the total cost of the socks by the number of pairs, we find that each pair of socks cost $4.99.
Step-by-step explanation:
The question asks us to calculate the cost of each pair of socks if Marsha paid with a $20 bill and received $5.03 in change after purchasing three pairs of socks. To find the cost per pair, we can follow these steps:
- Start with the total amount Marsha gave to the cashier: $20.
- Subtract the change Marsha received: $20 - $5.03 = $14.97.
- Divide this amount by the number of pairs of socks to find the cost per pair: $14.97 / 3 pairs = $4.99 per pair.
Therefore, each pair of socks cost $4.99.
