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

### Instruction:
 Rinda moja linahitaji futi 8.5 za kitambaa. Nguyen anahitaji kushona jozi 7 za rinda kwa ajili ya harusi. Ana kitambaa cha yardi 3.5. Anahitaji futi ngapi za kitambaa Nguyen bado kwa ajili ya rinda?


### Response:
 Rinda = 8.5 * 7 = <<8.5*7=59.5>>59.5 futi
3.5 yardi = 10.5 futi
59.5 - 10.5 = 49 futi
Rinda bado inahitaji futi 49 za kitambaa.
