3.

option c is correct

Step-by-step explanation:

1.

Given the equation:

Divide both sides by 16 we have;

⇒

2.

Given the equation:

8Z=64

Divide both sides by 8 to get Z;

3.

Given the formula:

Find C:

Divide both sides by AB we have;

or

$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)
