Which of the following would be the most logical first step to solving this quadratic equation? x2 - 4x + 16 = 2 a. divide both sides by x b. factor the left side into a perfect square. c. take the square root of both sides. d. subtract 2 from both sides.

$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)
