Blake bought 4  lollipops and 6 packs of chocolate. If each lollipop costs $2 and a pack of chocolate costs the same as four lollipops, how much change will Blake get back if he gave the cashier 6 $10 bills?
Four pieces of lollipop cost $2x 4 = $<T>multiply(2, 4)=8
A pack of chocolate costs $8 so 6 packs cost $8 x 6 = $<T>multiply(8, 6)=48
The total amount that she needs to pay is $8+ $48= $<T>add(8, 48)=56
Blake gave the cashier $10 x 6 = $<T>multiply(10, 6)=60
So, her change is $60 - $56 = $<T>subtract(60, 56)=4
