When solving negative one over three (x − 15) = −4, what is the correct sequence of operations? a Multiply each side by negative one over three , subtract 15 from each side
b Multiply each side by −3, add 15 to each side
c Multiply each side by negative one over three , add 15 to each side
d Multiply each side by 3, subtract 15 from each side

18a

step-by-step explanation:

simply because it is. it's the highest common factor

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
