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

### Instruction:
The basketball team sold 50 cupcakes for $2 each and 40 cookies for $0.5 each. Then the money from their sales was used to buy two basketballs that cost $40 each. The rest of the money was used to buy 20 bottles of energy drinks. How much does a bottle of energy drink cost?

### Response:
 Timu ya mpira wa kikapu ilipata $<<2*50=100>>100 kutokana na mauzo ya keki.
Timu ya mpira wa kikapu ilipata $<<0.5*40=20>>20 kutokana na mauzo ya biskuti.
Timu ya mpira wa kikapu ilipata jumla ya $<<100+20=120>>120.
Mipira miwili ya kikapu iligharimu $<<40*2=80>>80.
Hivyo, $120 - $80 = $<<120-80=40>>40 ilitumika kununua chupa 20 za vinywaji vya nishati.
Hivyo, kila chupa ya kinywaji cha nishati inagharimu $40/20 = $<<40/20=2>>2.
