Cahner goes to Chick-Fil-A and buys the 30-piece nugget originally priced at $13.45. He receives a 15% Student-of-the-Week discount. How much does Cahner pay for his meal after a 6% sales tax?

Respuesta :

Original price = $13.45

Discount = 15%

Taxes = 6%

1.- Calculate the price with discount

13.45 ---------------------- 100

x ----------------------- 15

x = (15 x 13.45) / 100

x = 201.75/100

x = $2.0175

13.45 - 2.0275 = $11.4325 Price with discount

2.- Price plus taxes

11.4325 --------------------- 100

x --------------------- 6

x = (6 x 11.4325) / 100

x = 68.595 / 100

x = $0.686

Payment = 11.4325 - 0.686

= $ 10.7466
