A meal cost $35.50 and there was no tax. If the tip was more than 10 percent but less than 15 percent of the price, then the total amount paid should be:

A. 40 - 42
B. 39 - 41
C. 38 - 40
D. 37 - 39
E. 36 - 37

The OA is B.

I'm really confused with this PS question. Experts, any suggestion about how to solve it? Thanks in advance.

10% tip
Tip = 10% of $35.50 = $3.55
TOTAL AMOUNT = $35.50 + $3.55 = $39.05

15% tip
Tip = 15% of $35.50 ≈ $3.55 + $1.77 ≈ $5.32
TOTAL AMOUNT ≈ $35.50 + $5.32 = $40.82

So, the TOTAL cost will be between $39.05 and $40.82

Only answer choice B meets this requirement

We can determine the lower end and the upper end of the meal cost plus the tip. The lower end is the meal cost plus 10% tip:

35.50 + 0.1(35.50) = 35.50 + 3.55 = $39.05

The upper end is the meal cost plus 15% tip:

35.50 + 0.15(35.50) = 35.50 + 5.33 = $40.83

Thus, the total amount paid is between $39 and $41.

Answer: B
