Question

After paying 8.5% sales tax and leaving a 20% tip, Gwyn paid $57.29. What was the cost of the meal before tax and tip? Round your answer to the nearest cent.

Answer 1

Answer:$33.41

Step-by-step explanation:

I converted the percentages to decimals and subtracted them from 1.

(Btw x stands for the cost before tip and tax)

This was the equation I came up with based on what was given to me;

57.29 = (1-0.085)x + (1-0.2)x

57.29=0.915x + 0.8x

57.29=1.715x

Divide both sides by 1.715 and should get 33.40524781

Since we are rounding to the nearest cent, the answer would be $33.41
