Anita and Maria went to the candy store. Maria bought 5 pieces of fudge and 3 pieces of bubble gum for a total of $5.70. Anita bought 2 pieces of fudge and 10 pieces of bubble gum for a total of $3.60. Determine the cost of 1 piece of bubble gum.

Answer 1

5f + 3g = 5.70
2f + 10g = 3.60

10f + 6g = 11.40
10f + 50g = 18.00

44g = 6.6
g = 66/44 = .15
so, f = 1.05
