### Instruction:
 Wasichana wa kikosi cha skauti walipata jumla ya $30 kutokana na kuuza biskuti tamu. Wanataka kwenda kuogelea. Itawagharimu $2.50 kwa kila mtu kwenda na watu 10 wanaenda. Kiasi kilichobaki ni kiasi gani?

 Itawagharimu $2.50 x 10 = $<<2.5*10=25>>25.
Wana $30 - $25 = $<<30-25=5>>5 kilichobaki.
