At the supermarket, the price paid for oranges is proportional to the mass purchased. Annie paid $6 for 2 kg of oranges. How much will Annie pay for 12 kg of oranges?
The price of 1 kg of oranges is $6 / 2 kg = $<T>divide(6, 2)=3.0/kg
So Ali will pay 12 kg * $3/kg = $<T>multiply(12, 3)=36 for 12 kg of oranges.
