What is the sales tax of a $15.95 video game if the tax rate is 7%

harina [27]

Answer:

$17.07

Step-by-step explanation:

Step 1: Find the percent of the price

Convert 7% to fraction

$= \frac{7}{100}\\\\=\frac{7}{100}\times \:15.95$

Multiply

$=\frac{7\times \:15.95}{100}$

Multiply the factors

$7\times \:15.95=111.65\\\\=\frac{111.65}{100}$

Divide

$\frac{111.65}{100}=1.1165\\\\=1.1165$

Step 2: Add the percent off to the original price

$15.95 + 1.1165\\\\= 17.0665$

Therefore, the total cost including tax in the nearest cent is 17.07 dollars
