Question

Kayla sells candy bars and cans of soda. She charges $3 for candy bars and $1 for soda. Yesterday shesold 70 items altogether and earned $100) How much candy did she sell? How much soda?

Answer 1

3c +s = 100

c + s = 70

subtract

3c -c = 100-70

2c = 30

c = 30/2 = 15 candies sold

s = 70-15 = 55 sodas sold
