Apples used to cost $1.6 per pound.  The price got raised 25%.  How much does it cost to buy 2 pounds of apples for each person in a 4 member family?
The price increase raised the price by 1.6*.25=$<T>multiply(1.6, 0.25)=0.4
So each pound of apples cost 1.6+.4=$2
2*4=<T>multiply(2, 4)=8 pounds of apples are bought
So the apples cost 8*2=$<T>multiply(8, 2)=16
