James started a food fight in his school's cafeteria, and the school administration is making him work off the cost of all the food he wasted at minimum wage ($8). James has to pay for 20 wasted pounds of meat at $5/pound, 15 wasted pounds of fruits and vegetables at $4/pound, 60 wasted pounds of bread products at $1.50/pound, and 10 hours of time-and-a-half pay for the janitorial staff, who normally make $10/hour. How many hours will James have to work to pay for everything?
Let's be accurate as possible and think first.
50
First find the total cost of the wasted meat: $5 / pound * 20 pounds = $100.

Then find the total cost of the wasted vegetables: $4 / pound * 15 pounds = $60.

Then find the total cost of the wasted bread products: $1.

50 / pound * 60 pounds = $90.

Then find the time - and - a - half rate for the janitors: $10 / hour * 1.

5 = $15 / hour.

Then multiply that by the number of hours to find the total janitorial cost: $15 / hour * 10 hours = $150.

Then add up all the costs to find the total cost of everything: $100 + $60 + $90 + $150 = $400.

Then divide the total James owes by his hourly wage to find how many hours he needs to work: $400 / $8 / hour = 50 hours.

.

So, the answer is 50
