Answer:
the number of hours for which the total cost would be the same is 4
Step-by-step explanation:
Let us assume the number of hours for which the total cost would be the same be x
The first equation would be
$80x + $20
And the second equation be $60x + $100
Now equate these two equations
$80x + $20 = $60x + $100
$80x - $60x = $100 - $20
$20x = $80
x = $80 ÷ $20
x = 4
Hence, the number of hours for which the total cost would be the same is 4
