Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Gharama ya nyama iliyopotea ni 20 * 5 = <<20*5=100>>100 dola.
Gharama ya matunda na mboga zilizopotea ni 15 * 4 = <<15*4=60>>60 dola.
Gharama ya bidhaa za mkate zilizopotea ni 60 * 1.5 = <<60*1.5=90>>90 dola.
Gharama ya wafanyakazi wa usafi ni 10 * (10+5) = <<10*(10+5)=150>>150 dola.
Jumla ya gharama ni 100 + 60 + 90 + 150 = <<100+60+90+150=400>>400 dola.
Masaa ya kufanya kazi ni 400 / 8 = <<400/8=50>>50 masaa.
