Question

Mr. Green paid $7.50 for a set of dry erase markers. He used a $2.00 coupon for his purchase. Write AND solve an equation that represents the difference between d, the original price of the markers and the coupon. Solve for d.

Answer 1

`d - 2 = 7.50`

$9.50

Explanation:

Given that:

Money paid by Mr. Green for a set of dry erase markers = $7.50

Coupon used for the purchase = $2.00

To find:

The equation and solution to represent the difference the original price
`d` of the markers and the coupon.

Solution:

Given that, the original price of the dry erase markers = $
`d`

Coupon amount = $2.00

Amount paid = $7.50

The equation can be made by subtracting the coupon amount from the original price and comparing it with the amount paid by Mr. Green for the purchase.

Original price = $(
`d` - 2)

`d - 2 = 7.50`

Solving the above equation by adding 2 on both the sides:

`d -2+2= 7.50+2\\\Rightarrow d = \$9.50`
