DAY 181
Three bags of jellybeans and two bags of chocolate chips cost $24. Two bags of jellybeans and four bags of chocolate chips also cost $24. How much is it for one bag of chocolate chips?

Answer:

$3.........Let J = jellybeans and C = chocolate chips.
3J + 2C = 2J + 4C
J = 2C
3(2C) + 2C = $24
8C = $24
C = $3
