Question

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?

Answer 1

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?

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

Answer 2

Explanation:

Consider Cotters paid "x" dollars:

According to given condition:

Moores paid "x+6" dollars.

Both paid total $30

Hence,

(x) + (x+6) = 30

Solving for x:

2x +6 = 30

2x = 30-6

2x = 24

x = 24/2

x = 12

So amount paid by Moores = x +6 = 12+6 = $18

*****To find number of pairs of skates: price of one pair must be given.
