What is a quartic function with only the two real zeros given?

x = -4 and x = -1

a. y = x4 + 5x3 + 5x2 + 5x + 4

b. y = x4 - 5x3 - 5x2 - 5x - 4

c. y = -x4 + 5x3 + 5x2 + 5x + 4

d. y = x4 + 5x3 + 5x2 + 5x - 5

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
