You show your student identification at a local restaurant in order to receive a 5% discount. You spend $12 for your meal at the restaurant. How much would your meal cost without the discount?
Let C be the cost without the discount
And the amount of the discount is 5% of this = .05C
Full Price - Discount = Final cost
C - .05C = 12
.95C = 12 divide both sides by ,95
C = 12/ .95 ≈ $12.63
