Question 302142
Here is the problem: 

Olivia bought 5 greeting cards that were each the same price. She used coupons worth $2.50. Alexandra bought 4 cards and used a $1.00 coupon. Each girl paid the same amount. What was the price of each card?

Let the price of the card be $x
Olivia
5 cards = 5x ---coupons worth 2.50 
So she paid 5x-2.5

Alexandria

4 cards so cost = 4x

coupons =$1

4x-1

they both paid same amount

5x-2.5=4x-1

5x-4x=2.5-1

x=1.5

Card costs $ 1.50
