Ineed to find the rate of change or slope of the line containing each pair of points.

2

Step-by-step explanation:

As we move from (1/6, 1/3) to (1/4, 1/2), x increases by 1/12, and y increases by 1/6.  Thus, the slope is m = rise / run = (1/6) / (1/12), OR 12/6, or 2.  

The desired rate of change / slope is m = 2.

john earns $14.00 for two hours of work.

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
