Matt lives on popcorn and seafood salads. The price of popcorn is 1 dollar per bag and the
price of seafood salads is 2 dollars each. Matt allows himself to spend no more than 13 dollars a
day on food. He also restricts his consumption to 5,500 calories per day. There are 1,000 calories
in a bag of popcorn and 500 calories in a seafood salad. If he spends his entire money budget each
day and consumes no more calories than his calorie limit:
(a) he can consume up to 3 bags of popcorn per day, but no more.
(b) he can consume up to 1 bags of popcorn per day, butno more.
(c) he can consume up to 5 seafood salads per day, but no more.
(d) he can consume up to 4 bags of popcorn per day, but no more.
(e) None of the above.

The answer to this question, why can't it be c) also. Because solving the equation-
p+2s=13 & 2p+s=11, we are getting p=3 & s=5..
