Answer: 6 pairs of skates.
Use the following information to solve the problem. At Open Skate Night, admission is $3.75 with a membership card and $5.00 without a membership card. Skate rentals are $3.00. The Moores paid $6 more for skate rentals than the Cotters did. Together, the two families paid $30 for skate rentals. How many pairs of skates did the Moores rent?
Step-by-step explanation:
Given;
Skate rental = $3
Total cost spent by the two families = $30
If the cost spent by the cotters is
$3×x = $3x
Where x is the number of pairs of skates that the cotters rent
The cost spent by the moores can be written as;
$3x + 6
Total cost spent by the two families is
3x + 3x + 6 = 30
6x + 6 = 30
6x = 24
x = 24/6
x = 4
So, the number of pairs of skates that the cotters rent is 4.
The moores spent $6 more than the cotters...
At $3 per pair, $6/$3 = 2
So, the number of pairs of skates that the moores rent is 4+2 = 6
