A restaurant meal cost $35.50 and there was no tax. If the tip was more than 10 percent but less than 15 percent of the cost of the meal, then the total amount paid must have been between
(A) $40 and $42
(B) $39 and $41
(C) $38 and $40
(D) $37 and $39
(E) $36 and $37
10% tipTip = 10% of $35.50 = $3.55
TOTAL AMOUNT = $35.50 + $3.55 = $39.05
15% tipTip = 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
