Suppose Mike’s exponential model is the best fit for a sample of two-variable data collected from a population of 30 voters. His model has the following values for a and b. a = 4039.22 b = 0.1719 How does Mike project Y from a value of X in the voter population? Mike uses the greatest value of a or b Mike projects y using the model y = 4039.22 x + 0.1719 Mike multiplies a and b Mike uses the values of a and b in the equation

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
