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

### Instruction:
Four people in a law firm are planning a party. Mary will buy a platter of pasta for $20 and a loaf of bread for $2. Elle and Andrea will split the cost for buying 4 cans of soda which cost $1.50 each, and chicken wings for $10. Joe will buy a cake that costs $5. How much more will Mary spend than the rest of the firm put together?

### Response:
 Mary atatumia $20 + $2 = $<<20+2=22>>22.
Elle, Andrea, na Joe watatumia $1.50 * 4 + $10 + $5 = $<<1.5*4+10+5=20.5>>20.5.
Hivyo, Mary atatumia $22 - $20.5 = $<<22-20.5=1.5>>1.5 zaidi kuliko wengine wote katika kampuni hiyo.
