work pleaseeeeeeeeeeeeeeeeeeee

Answer 1

Answer:  $76.50

Step-by-step explanation:

110 x .35 = 38.50

110 - 38.50 = 71.50

71.50 x .07 = 5.00

71.50 + 5.00 = 76.50

Answer 2

The cost of the calculator is $ 76.505

Solution:

Given that,

A calculator is listed for $110 and is on clearance for 35% off sales tax is 7%

Then,

Cost = $ 110

Discount = 35 %

Thus,

Cost before tax = 110 - 35 % of 110

$Cost\ before\ tax = 110 - \frac{35}{100} \times 110 \\\\ Cost\ before\ tax = 110 - 0.35 \times 110 \\\\Cost\ before\ tax = 110 - 38.5 \\\\Cost\ before\ tax = 71.5$

Then,

sales tax = 7 %

Cost after tax = 71.5 + 7 % of 71.5

$Cost\ after\ tax = 71.5 + \frac{7}{100} \times 71.5 \\\\Cost\ after\ tax = 71.5 + 0.07 \times 71.5 \\\\Cost\ after\ tax = 71.5 + 5.005 \\\\Cost\ after\ tax = 76.505$

Thus cost of the calculator is $ 76.505
