In class, students could purchase four goods, namely, a can of coke, a snickers bar, a twinkie, and a carton of milk. They had an income of five dollars to be spent on each of the four goods. Each student had to spend all five dollars. On Day 2, the price of Snickers doubled to two dollars. On Day 3, the price of Snickers went back down to $1 but income increased to $8. All the students' quantities were summed together and gave the following results.

	Day 1: Market Quantities	Day 2: Market Quantities	Day 3: Market Quantities
Can of Coke	39	42	63
Snickers Bar	55	41	82
Twinkie	35	28	77
Carton of Milk	54	41	69
