The total amount for the meal was between 35.5*1.1=39.05 and 35.5*1.15=~41. Only option which covers all possible values of the meal is B.

Answer: B.

just came across this question in OG13 and I thought answer should be A

Let Total paid be T
so 39.05<T<40.83. So it fits "inside" A, 40<T<42 so to speak.
B states that 39<T<41, which works for the right hand side of T but not for the left. (E.g. if T is 39.01, then tip is only 9.89% of 35.50 - less than 10% requirement in the question)

How does 39.06 fit into --- 40<39.06<42????. So option B makes sense.

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 total amount paid must have been betweem:

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

I'll post the question in the next post. Thanks!

Hi,

I'm stuck on something rather trivial on this relatively easy question.

After calculating 10%, I get 39.05and 40.82. I didn't pick B because I noticed that 39 is less than $39.05, so a number like 39.02 would've made this wrong. Can someone explain why i'm wrong?

Thanks!
