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

### Instruction:
Max has a collection of stamps in three colors: 20 red stamps, 80 blue stamps and 7 yellow ones. He is trying to sell the whole collection. He already sold 20 red stamps for the price of $1.1 for each stamp and 80 blue stamps for the price of $0.8 for each stamp. What price did he need to set for each yellow stamp to be able to earn the total of $100 from the whole sale?

### Response:
 Max ana stempu 20 nyekundu na stempu 80 za bluu zilizobaki.
Anahitaji kuuza stempu 7 za manjano ili apate $100.
Hivyo anahitaji kuuza stempu 20 nyekundu kwa $1.1 kila moja, stempu 80 za bluu kwa $0.8 kila moja, na stempu 7 za manjano kwa $Y kila moja.
Jumla ya pesa anayohitaji kupata ni 20 * $1.1 + 80 * $0.8 + 7 * $Y = 100.
Hii inalingana na 20 * $1.1 + 80 * $0.8 + 7 * $Y = 100.
Hivyo, bei ya kila stempu ya manjano ni $Y = 100 - 20 * $1.1 - 80 * $0.8 = $<<100-20*1.1-80*.8=6.7>>6.7.
