Compute the sales tax on the following transactions. an article retails for $38.50. the city sales tax is 4%, and the federal excise tax is 7%. how much is the total tax? a. 1.54
b. 2.70
c. 4.24
d. 34.26

The answer is C) 4.24

4% + 7% = 11%

to get 11% of 38.50 you move the decimal two spaces to the left on the percent and multiply that number by the other number.

11% ---> .11

38.50 x .11= 4.24.

I hope this answer gave you a better understanding on how to work with percentages! :) Have a good day :)
