For every 12 cans you recycle, you receive $0.50, and for every 5 kilograms of newspapers, you receive $1.50. If your family collected 144 cans and 20 kilograms of newspapers, how much money would you receive?
There are 144/12 = <T>divide(144, 12)=12.0 sets of 12 cans that the family collected.
So, the family would receive $0.50 x 12 = $<T>multiply(0.5, 12)=6.0 for the cans.
There are 20/5 = <T>divide(20, 5)=4.0 sets of 5 kilograms of newspapers that the family collected.
So, the family would receive $1.50 x 4 = $<T>multiply(1.5, 4)=6.0 for the newspapers.
Therefore, the family would receive a total of $6 + $6 = $<T>add(6, 6)=12
