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

### Instruction:
There were 90 jellybeans in a jar. Samantha snuck 24 jellybeans out of the jar, without being seen. Shelby ate 12 jellybeans from the jar. Their mom, Shannon, refilled the jar with half as much as Samantha and Shelby took out. How many jellybeans are in the jar now?

### Response:
 Idadi ya jellybeans kwenye kopo ni 90 - (24 + 12) = <<90-(24+12)=54>>54.
Baada ya mama kujaza kopo na nusu ya zile zilizoondolewa, kopo ina jellybeans 54 + (24 + 12) / 2 = <<54+(24+12)/2=90>>90 sasa.
