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

### Instruction:
Shara collects shells. She had 20 shells before she went on vacation. On vacation, she found 5 shells per day for 3 days. Then he found 6 shells on the fourth day. How many shells does she have now?

### Response:
 Shara alikusanya magamba 5 x 3 = <<5*3=15>>15 kwa siku 3.
Hivyo, alikusanya jumla ya magamba 15 + 6 = <<15+6=21>>21 kutoka likizoni.
Hivyo, sasa ana jumla ya magamba 20 + 21 = <<41=41>>41.
