Question

a group of students went to lunch. the bill before the sales tax and trip was $37.50 a sales tax of 8% was added. the group then tipped 18% on the amount after sales tax was added. what was the amount in dollars of the sale tax

Answer 1

100+8=108

108% of 37.50=1.08 times 37.50=40.5
(40.5-37.50=3, tax was 3)
18% tip
100+18=118
118% of 40.5=1.18 times 40.5=47.79

amount total was $47.79
tax was $3
