The listed price of the video game was $34, but the price with tax came to $37.40. Find the percent sales tax.
Katarina [22]

Answer:

10%

Step-by-step explanation:

we want to find what % of 34 is 37.40

so, we will use the following equation:

\frac{part}{whole} = \frac{percent}{100}

for this scenario:

part = 37.40

whole = 34

percent = x

now plug in:

\frac{37.40}{34} = \frac{x}{100}                         cross multiply

34x = (37.40)(100)

34x = 3740                      divide both sides by 34

x = 110%

now we know that with tax, we paid 110% of the video game's price

110 - 100 = 10%

so the percent sales tax is 10%

<u>just to check... </u>

34 • 1.10 = $37.40

or

34 • .10 = 3.40

34 + 3.40 = 37.40
