Nate downloaded 20 songs total with three times as many pop songs, three times as many rock songs, and the same number of hip hop songs as Mark. Which system of equations represents their music choices? answer choices are:
A. x + y + z = 10
5x + 2y + 3z = 28
3x + 3y + z = 20
B. x + y + z = 10
2x + 5y + 3z = 28
3x + 3y + z = 20
C. x + y + z = 10
5x + 2y + 3z = 28
3x + 3y + 3z = 20
D. x + y + z = 10
2x + 3y + 5z = 28
x + 3y + 3z = 20

you have 6 cupcakes

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
