Claire purchases a new dress for the prom. The dress is priced $160, but it is on sale for 30% off. Claire’s aunt works at the s
djverab [1.8K]

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
