Please help i'm confused thank you !!
A car rental company charges $27 per day for the use of a car. In addition, it also charges 60¢ for every mile or part thereof traveled. Mr. Li paid $453.60 for renting a car for 3 days. Find the distance Mr. Li traveled with this car.

using Y = mx +b equation

453.60 = .60x + 81     27 *3 = 81

Move the 81 over to the other side you end up with:

372.60 = .60x

divide each side by .60

x = 621

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
