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

### Instruction:
Tommy is making 12 loaves of bread. He needs 4 pounds of flour per loaf. A 10-pound bag of flour costs $10 and a 12-pound bag costs $13. When he is done making his bread, he has no use for flour and so he will throw away whatever is left. How much does he spend on flour if he buys the cheapest flour to get enough?

### Response:
 Anahitaji kilo 48 za unga kwa sababu 12 x 4 = <<12*4=48>>48
Anahitaji mifuko 4.8 ya unga wa kilo 10 kwa sababu 48 / 10 = <<48/10=4.8>>4.8
Hivyo, anahitaji kununua mifuko 5 ya unga kwa sababu 4 < 4.8 < 5
Anatumia $50 kwa unga ikiwa ananunua unga huu kwa sababu 5 x 10 = <<5*10=50>>50
Anahitaji mifuko 3 ya unga wa kilo 12 kwa sababu 48 / 15 = <<48/15=3.2>>3.2
Angetumia $39 kwa mifuko ya unga wa kilo 12 kwa sababu 3 x 13 = <<3*13=39>>39
Anatumia $50 kwa unga ikiwa ananunua unga wa bei rahisi kwa sababu 50 < 39
