Question

3. Mrs. Noah’s bill, before tax, is $50. The sales tax rate is 3%. Mrs. Noah decides to leave a 2% tip for the gate keeper based on the pre-tax amount. How much will the total bill be, including tax and tip?

Answer 1

Answer: The total bill will be $52.5

Explanation:

Hi, to answer this question, first we have to multiply the amount of the bill before tax (50) by the sale tax rate in decimal form (divided by 100)

Mathematically speaking:

50 x (3/100) = 50 x 0.03 = $1.5 (sales tax amount)

Next, we have to multiply the amount of the bill before tax (50) by the tip percentage in decimal form:

50 x (2/100) = 50 x 0.02 = $1 (tip amount)

Finally, we have to add both amounts to the original bill:

50+1.5+1 = $52.5
