PLS HELP. You can model the arch of a building by using the equation y = -1/3 (x+6)(x-6) where x and y are measured in feet. The x-axis represents the ground. Find the width of the arch at the ground.

$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)

(23*2)-12=x     x=34
