Rodolfo Buchanan · Answer 1

Step-by-step 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
