Question

A skating rink charges a group rate of $9 plus a fee to rent each pair of skates. A family rents 7 pairs of skates and pays a total of $30.

Answer 1

Answer: One pair of skates costs a total of $3

Step-by-step explanation: 30 (Total) - 9 (Fee) ÷ 7 (Pairs of skates)

Total - Free ÷ Pair of skates

Answer 2

9+7x=30 would be your equation

Solve for x.
Subtract 9 from both sides
7x= 21 and divide by 7

X= 3
