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)

Lower End:
NA=35.50(1+10/100)
NA=35.50(110/100)
NA=39.05

Upper End:
NA=35.50(1+15/100)
NA=35.50(115/100)
NA=40.825

Rounding = 39-41

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

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!

(B) $39 and $41
(C) $38 and $40
(D) $37 and $39
(E) $36 and $37



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

(D) $37 and $39
(E) $36 and $37


\(10 < tip < 15\)

Min tip = 10.01
Max tip = 14.99

Min value of meal is 110.01 % 35.50 = 39.05
Max value of meal is 114.99 % 35.50 = 40.82

Hence, answer will be (B) $39 and $41
