Question

Hazel has out of town guest coming to visit. She is going to hire a cleaning service to tidy up her house. The maids charge her $80 an hour plus one time service fee of $20. Team clean chargers $60 an hour plus a one time service fee of $100 write and solve an equation to find the number of hours for which the total cost will be the same for the two cleaning services.

Answer 1

the number of hours for which the total cost would be the same is 4

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
