Question

I solved part C I just need help with part D

Answer 1

1) Gathering the data

8% sales tax

2 DVDs' price: $21.60 (after taxation)

2) To find out how much for the DVDs without the sales tax, let's write this equation.

P for the price without tax, 1.08 the sales tax factor, $21.60 the full price

p (1.08) =21.60 Let's divide both sides by 1.08

p= 21.60 /1.08

p= 20

3) So the price without tax, is $20
