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

### Instruction:
Aubree saw 20 beavers and 40 chipmunks by a tree when going to school and scared them away when they saw her. While coming back from school, she realized the number of beavers had doubled and the number of chipmunks had decreased by 10. What's the total number of animals she saw that day?

### Response:
 Akiwa anaenda shule, aliwaona wanyama 40+20 = <<40+20=60>>60.
Idadi ya beavers iliongezeka mara mbili hadi 20*2 = <<20*2=40>>40 beavers.
Idadi ya chipmunks ilipungua hadi 40-10 = <<40-10=30>>30 chipmunks.
Aliwaona wanyama 40+30+60 = <<40+30+60=130>>130 siku hiyo.
