Hector has $100 in savings and makes $7.50 per hour. Luis has $80 in savings and earns $12.75 for each hour worked.

They work together for the same number of hours, and they save all of the money they earn. Luis wants to know how many hours he has to work to have the same amount of money in savings as Hector. Luis sets the expression representing his savings given his hours worked equal to the expression for Hector.

Which equation should Luis use? Which is the logical first step to find the solution, and how can taking the step be justified?

A
The equation is 7.50h + 100 = 12.75h + 80. The logical first step is to subtract 7.50h from both sides using the subtraction property of equality.

B
The equation is 7.50h + 100 = 12.75h + 80. The logical first step is to add 80 to both sides of the equation using the additive property of equality.

C
The equation is 12.75h + 100 = 7.50h + 80. The logical first step is to subtract 7.50 from both sides using the subtraction property of equality.

D
The equation is 12.75h + 100 = 7.50 + 80. The logical first step is to subtract 80 from both sides of the equation using the subtraction property of equality.
