Answer:
(x - 3) * 6 = 72
jack earns $ 15 an hour and samuel $12 an hour
Step-by-step explanation:
we know that samuel earns 3 dollars less than jack, let's say that "x" is what jack earns, in addition to this we know that samuel earns a total of 72 dollars in 6 hours, therefore we have to:
(x - 3) * 6 = 72
this would be the equation to determine x, we solve it:
6 * x - 18 = 72
6 * x = 72 + 18
x = 90/6
x = 15
which means that jack earns $ 15 an hour and samuel $12 an hour
