Given a polynomial f(x), if (x + 7) is a factor, what else must be true? a) f(0) = 7 b) f(0) = −7 c) f(−7) = 0 d) f(7) = 0

$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)
