Question

A woman bought a coat for $99.95 and some gloves for $7.95. If the sales tax was 7%, how much did the purchase cost her? (Round your answer to the nearest cent.)

Answer 1

Answer: $115.5

Step-by-step explanation:

The woman bought a coat for $99.95 and some gloves for $7.95. This means that the total amount of money that the woman would have paid for the coat without tax is

99. 95 + 7.95 = $107.9

If the sales tax was 7%, then the amount paid as sales tax would be

7/100 × 107.9 = 0.07 × 107.9 = $7.553

Therefore, the amount that she would pay to purchase the coat and the gloves is

107.9 + 7.553 = 115.453

= $115.5 rounded up to the nearest cent.

Answer 2

The woman spent

$99.95+7.95=107.9$

dollars in total. Given the 7% sales tax, it means that she actually paid 107% of this amount. So, the final price was

$107.9\cdot\dfrac{107}{100}=1.079\cdot 107=115.453\approx 115.45$

dollars.
