The Moores family 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?

Moores Family Paid = 6 dollars mores for skate rental than the cotters did.

30 dollars = the total amount they paid for skate rentals.

Let Family Moore have the variable X

Let the Family Cotters have the variable Y

=> x = y + 6

=> y = 30 - 6 / 2

First, let’s solve the Y

=> Y - 30 - 6 / 2

=> Y = 24 / 2

=> y = 12

Now, let’s solve for X

=> X = y + 6

=> x = 12 + 6

=> X = 18
