Question

Abbey gets paid a flat rate of $10.00 to mow her neighbor's lawn plus an additional $5 per hour to rake the leaves. The money she earns is represented by the equation m = 5h + 10, where m represents the amount of money she earns, in dollars, and h is the number of hours she rakes leaves for. Which of the following equations can be used to find h, the number of hours she rakes leaves for?

Answer 1

m = 5h + 10.....so basically we solve for h subtract 10 from both sides m - 10 = 5h divide both sides by 5 (m - 10)/5 = h

Answer 2

h =( m - 10)/5

Explanation:

We were given the initial equation

m = 5h + 10, to calculate the total money she earns in dollar per hour work. So to prove the answer, she earns $15/hr according to the question because she earns $10 for mowing and $5 for taking.

Substituting $15 into m gives us

15 = 5h + 10

5h=15-10

5h= 5

h = 1

h is one hour, so this proves h =( m - 10)/5
