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

### Instruction:
Alyssa and Abigail need to collect 100 empty cans for their Science project. As of today, Alyssa collected 30 while Abigail collected 43 empty cans. How many more empty cans should they collect?

### Response:
 Alyssa na Abigail wamekusanya jumla ya makopo 30 + 43 = <<30+43=73>>73 kufikia leo.
Hivyo, bado wanahitaji kukusanya makopo 100 - 73 = <<100-73=27>>27 zaidi.
