Each month, Miss Patrick spends $60 on transportation to work, and earns $24.50 per hour. Each month, Mr. Shah spends $150 on lab equipment and earns $32.50 per month. How many hours do they have to work during the same amount

3 hours for miss patrick 5 hours for mr shah

Answer: they have to work for 11.25 hours.

Step-by-step explanation:

Let x represent the number of months for which they have to work to make the same amount.

Each month, Miss Patrick spends $60 on transportation to work, and earns $24.50 per hour. This means that if she works for x hours in a month, the total amount that she would have is

24.5x - 60

Each month, Mr. Shah spends $150 on lab equipment and earns $32.50 per month. This means that if he works for x hours in a month, the total amount that he would have is

32.5x - 150

For them to have the same amount, the number of months would be

32.5x - 150 = 24.5x - 60

32.5x - 24.5x = - 60 + 150

8x = 90

x = 90/8

x = 11.25 hours
