### Instruction:
 Patrick amekuwa akijiwekea akiba ya pesa ili kununua baiskeli inayogharimu $150. Alikuwa amejiwekea akiba nusu ya bei lakini kisha akamkopesha rafiki yake $50. Patrick ana pesa kiasi gani sasa?


### Response:
 Nusu ya bei ya baiskeli ni 150 / 2 = $<<150/2=75>>75.
Pesa ambazo Patrick anazo sasa ni 75 - 50 = $<<75-50=25>>25.
