Nathan Smith · Answer 1

Number of hours = (Total earnings + Total costs) / $15

Mika worked 18 hours

Step-by-step explanation:

Mika's earnings function is:

Total earnings = Total Payment-Total costs

The total payment depends on the number of hours Mika took to pint the neighbor's fence:

Total earnings = $15x-Total costs

Now we transform this equation to know the number of hours worked:

Total earnings+Total costs = $15x

(Total earnings + Total costs) / $15=x

x = $174+$96/$15

x = 18

Mika worked 18 hours
