Question

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?

Answer 1

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

Answer 2

x + x + 6 = 2x + 6 = 30

x = 12

(12 + 6)/3
