Melinda and Marcus each have a job. Melinda earns $12 an hour. She also receives a $75 weekly bonus.

Melinda made a table to show how much she earns in a given week.
Hours 0 5 10 15 20 25 30 35 40
Weekly Earnings 75 135 195 255 315 375 435 495 555

Marcus earns $15 an hour.

Marcus wrote an equation to determine how much he earns for a given number of hours in a given week.

According to given information,
Equation of Melinda Earning = 75 + 12x
Equation of Marcus Earning = 15x
Where, x = Number of hours they worked.

Now, we need to calculate when they will have same amount of money, so for that instance they shall equal to each other.
75 + 12x = 15x
15x - 12x = 75
3x = 75
x = 75/3
x = 25

After 25 hours, they will have the money = 15(25) = $375

So, your final answer is $375

Hope this helps!
