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

### Instruction:
It is the rainy season in central Texas.  It rained for 7 hours on Monday at a rate of 1 inch per hour.  On Tuesday, it rained for 4 hours at a rate of 2 inches per hour, and on Wednesday, it rained for 2 hours at a rate of twice that of the previous day.  What is the total combined rainfall, in inches, for these three days?

### Response:
 Jumatatu, inchi 1 ya mvua ilinyesha kwa masaa 7, kwa jumla ya 1*7 = <<7*1=7>>7 inchi.
Jumanne, inchi 2 za mvua zilinyesha kwa masaa 4, kwa jumla ya 2*4 = <<2*4=8>>8 inchi.
Mara mbili ya kiwango cha Jumanne ni 2*2 = <<2*2=4>>4 inchi kwa saa.
Jumatano, masaa 2 ya mvua kwa kiwango cha 4 inchi kwa saa ni 4*2 = <<4*2=8>>8 inchi.
Jumla ya mvua kwa siku hizi tatu ni 7+8+8 = <<7+8+8=23>>23 inchi.
