Answer:
You are supposed to find how much 2 packages of chicken costs when each package is 12.36, 1/2 lb of broccoli when one pound costs 1.98, and 1 gallon of milk with 3.49 per gallon. After that, you need to find how much Susan paid with when she recieved 80 cents in change.
(2*12.36)+(1.98*0.5)+3.49+0.80=x
find out what x is to get the answer.
