Answer:
10%
Step-by-step explanation:
we want to find what % of 34 is 37.40
so, we will use the following equation:
for this scenario:
part = 37.40
whole = 34
percent = x
now plug in:
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
