Which function in vertex form is equivalent to f(x) = x2 + 8 – 16x?

a. f(x) = (x – 8)2 – 56
b. f(x) = (x – 4)2 + 0
c. f(x) = (x + 8)2 – 72
d. f(x) = (x + 4)2 – 32

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
