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

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
