Suppose you have a $7.50 off coupon of at the fabric store you buy fabric that cost $14 per yard write an equation that models the total amount of money you you pay if you buy x yards of fabric
If you have a $7.50 off coupon, the total amount of money you pay can be modeled by the equation:
Total amount = (Cost per yard * number of yards) - Coupon amount
In this case, the cost per yard is $14 and the coupon amount is $7.50. Plugging in these values, the equation becomes:
Total amount = (14 * x) - 7.50
