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

### Instruction:
Ali's class wants to order 35 English textbooks and 35 geography textbooks. Knowing that a geography book costs $10.50 and that an English book costs $7.50, what is the amount of this order?

### Response:
 Kwa vitabu vya jiografia, unatumia 35 * $10.50 = $<<35*10.5=367.5>>367.5
Kwa vitabu vya Kiingereza, unatumia 35 * $7.50= $<<35*7.5=262.5>>262.5
Hivyo, jumla ya matumizi ni $367.5 + $262.5 = $<<367.5+262.5=630>>630
