Answer: $35
Explanation:
lets create an equation
x is going to be the amount of money gained by raking leaves
(63.50 + x) - 44.99 = 53.51
now remember, whatever you do to one side, you do to the other side.. oppositely.
so lets add 44.99 to both sides, either side of the equal sign, because the opposite of -44.99 is +44.99
63.50 + x = 98.50
now subtract 63.50 from both sides
x = 35
