Answer 1

Answer:

Online store will save the most money

Step-by-step explanation:

Amount used in Physical store

Batteries    2packs      @$5.99     cost = $5.99*2=$11.98

Stereo        1 system     @$100      cost = $100*1=$100

CDs             3 CDs        @$7.95     cost = $ 23.85

Total cost= $11.98+$100+$23.85= $135.83

Applying the 10% off coupon = 90/100 * $135.83 =$ 122.25

Applying sale tax 5% = 105/100 * 122.25=$128.36

Amount  to spend when using physical store= $128.36

Now calculate for the online store

Batteries     2packs     @$4.99       cost= $4.99*2=$ 9.98

Stereo         1 system    @$90         cost= $ 90 *1= $90

CDs              3  CDs      @$8.95       cost = $8.95*3=$26.85

Total cost=$9.98+$90+$26.85=$126.83

Applying the 5% off coupon= 95/100*126.83=$120.49

Applying the sale tax, $6.99+$120.49=$127.48

Comparing the two ways,

Physical store= $128.36

Online store=$127.48

Online store will save the most money by ($128.36-$127.48)=0.88
