Answer:
[tex]d - 2 = 7.50[/tex]
$9.50
Step-by-step 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 [tex]d[/tex] of the markers and the coupon.
Solution:
Given that, the original price of the dry erase markers = $[tex]d[/tex]
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 = $([tex]d[/tex] - 2)
[tex]d - 2 = 7.50[/tex]
Solving the above equation by adding 2 on both the sides:
[tex]d -2+2= 7.50+2\\\Rightarrow d = \$9.50[/tex]
