Let f(x)=-2-7 and g(x)=-4+3. find (f o ) a.-53 b.23 c.-9 d.3

(A) -53

Step-by-step explanation:

g(x) = -4x + 3

g(-5) = -4(-5) + 3

       = 20 + 3

       = 23

                             f(x) = -2x - 7

                           f(23) = -2(23) - 7

                                   = -46 - 7

                                   = -53

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
