1.)Lisa and Beverly had just $5 to spend for an after-school snack. They could have bought 2 hamburgers and 1 carton of milk with no change back or 1 hamburger and 2 cartons of milk with 40 cents change back. How much does a carton of milk cost?
2.)If you buy six pens and one mechanical pencil, you'll get only $1 change from your $10 bill. But if you buy four pens and two mechanical pencils, you'll get $2 change. How much does each pen and each pencil cost?
3.)One number is 16 more than another. If the smaller number is subtracted from two-thirds of the larger number, the result is one-fourth of the sum of the two numbers. Find the numbers.
Thank you very much! An answer as immediate as possible would be greatly appreciated.

Question 185589: Hello, I'm trying to help my son with his math homework but it's been 30 years since I had to do math and I can't remember enough to help him.
One example of the type of questions he has would be:
tennis consumes 25 calories a minute
cycling consumes 35 calories a minute
The player plays both sports for a total of 50 minutes consuming 1450 calories. How long did he play tennis?
I've been trying to come up with something like 25x + 35y = 1450 but I can't go from there.
I'd be grateful if you could quickly give me some idea how to do the above.
Thanks
John Mullany
