Question

pablo and greg both received gift cards for the same amount to a popular clothing store.Pablo bought 2 pairs of jeans and has $36 remaining on his gift card. greg bought 5 pairs of the same jeans and has no money left on his gift card. what is the cost of 1 pair of jeans.

Answer 1

12

Explanation:

let y be the value of the gift card and x be the cost of a pair of jeans

The equation for Pablo

y-2x=36 Add 2x to both sides

y=36+2x

The equation for Greg

y-5x=0 Add 5x to both sides

y=5x

Now that we have isolated y in both equations, lets set them equal to each other

36+2x=5x Subtract 2x from both sides

36=3x Divide both sides by 3

12=x x=12, which means that 1 pair of jeans costs $12
