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

### Instruction:
Salaria is growing oranges this summer. She bought two types of trees. She has 50% of tree A and 50% of tree B. Tree A gives her 10 oranges a month and 60% are good. Tree B gives her 15 oranges and 1/3 are good. If she gets 55 good oranges per month, how many total trees does she have?

### Response:
 Kila mti A humletea machungwa 6 mazuri kwa mwezi kwa sababu 10 x .6 = 6
Kila mti B humletea machungwa 5 mazuri kwa mwezi kwa sababu 15 x (1/3) = <<15*(1/3)=5>>5
Kwa wastani, mti mmoja humletea machungwa 5.5 kwa mwezi kwa sababu .5(6) + .5(5) = 5.5
Ana miti kumi jumla kwa sababu 55 / 5.5 = <<55/5.5=10>>10
