Answer:
360+12x=279+15x
The two costs would be the same when both companies charge 27 hours.
Step-by-step explanation:
From the information given, you need to find the number of hours where both companies charge the same and to do that, you can write an equation where Home Improvement cost is equal to Ace Hardware cost:
360+12x=279+15x, where x is the number of hours
Now, you can solve for x:
360-279=15x-12x
81=3x
x=81/3
x=27
According to this, the answer is that the two costs would be the same when both companies charge 27 hours.
