Patrick has been saving money to buy a bicycle that costs $150. He saved half the price but he then lent $50 to his friend. How much money does Patrick have now?
Half of the price of the bicycle is 150 / 2 = $<T>divide(150, 2)=75.0
The money that Patrick has now is 75 – 50 = $<T>subtract(75, 50)=25
