Question

A couple goes out to dinner, which costs $45. To the nearest dollar, what should they pay in total, if they tip 15% on the bill?

Here are the options,

(1) $45
(2) $50
(3) $51
(4) $52
(5)$ 53
--------------------
The answer I choose is (3). Can someone check if I got the answer right, and if I could have the right answer.

Answer 1

A couple will pay 100% + 15% = 115%

115% = 115 / 100 = 1.15

1.15 • $45 = $51.75

To the nearest dollar, they pay in total $52 because different betwen $52 and $ 51.75 is $0.25

Different betwen $51.57 and $ 51 is $0.75

$ 52 is closer to $ 51.75 than $ 51

Answer (4)

Answer 2

15% of 45 is 6.75 so in order to get 115% you would take 45 and 6.75 and add them to get 51.75 and if you round that to the nearest dollar you get 52
