Answer 1

Answer:

$Total = \ 103.20$

Step-by-step explanation:

Given

$Amount =\ 160$

$D_1 = 30\%$ --- first discount

$D_2 = 10\%$ --- second discount

$Sales\ Tax = 7.5\%$

Required

Determine the amount paid

First, we add the total discount:

$D = D_1 + D_2$

$D = 30\% + 10\%$

$D = 40\%$

If she got a discount of 40%, then she paid 60% (i.e. 100% - 40%)

So:

$Amount = 60\% * \ 160$

$Amount = \ 96$

Calculate the sales tax

$Sales\ Tax = 7.5\% * \ 96$

$Sales\ Tax = \ 7.2$

$Total = \ 96 + \ 7.2$

$Total = \ 103.20$
