Formula for finding the perimeter of a rectangle is p = 2l + 2w. if you know the perim 1. w = p2 – l 2. w = p – 2l – 2 3. w = p2 – 2l 4. w = p4l

W = P/2 - L

Step-by-step explanation:

WE need to make W the subject of

P = 2L + 2W

2W = P - 2L

W = ( P - 2L) / 2

or W = P/2 - L

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
