A. What is the total cost if the coupon is applied to the digital camera?

B. What is the total cost if the coupon is applied to the extra battery?

C.To which item should Eric apply the discount? Explain.

D. Eric has to pay 8% sales tax after the coupon is applied. How much is his total bill?

Answer 1

Explanation:

A. 95*0.10=9.50

95.00-9.50=85.50

85.50+15.99=$101.49

B. 15.99*0.10=1.599

15.99-1.599=14.391

14.391+95=109.391

But it’s money, so the answer is $109.39

C. Eric should apply the discount to the digital camera because the total cost is cheaper than applying the discount to the extra battery.

D. 95+15.99=110.99

110.99*0.10=11.0990

110.99-11.099=99.891

99.891*0.08=7.99128

99.891+7.99128=107.88228

Since it is money, the answer is $107.88
