Kendra was asked to find the number of students who planned to attend the evening symphony performance. She was told that 40 percent of the 50 students planned to attend. Kendra’s work is shown below. StartFraction part Over whole EndFraction = StartFraction 40 times 2 Over 100 times 2 EndFraction = StartFraction 80 Over 200 EndFraction

What mistake did Kendra make?
Kendra should have multiplied by 4 instead of multiplying by 2.
Kendra should have divided by 2 instead of multiplying by 2.
Kendra should have added 40 and 50.
Kendra should have subtracted 40 from 50.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
