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