The graph of the linear function f passes through
the points (a, l) and (1,b) in the xy-plane. If the
slope of the graph of f is 1, which of the
following is true? ton and to 1 oqofe at
olestie
A) a-b=1
B) a+b=1
C) a-b= 2
D) a+b= 2

both equations and proportions are better.

addition

step-by-step explanation:

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
