At the candy store, M&Ms and Skittles are sold for $0.50 per ounce. Kevita puts some M&Ms in a bag and then added 8 ounces of Skittles. The total cost for her bag of candy is $6.50.
Kevita and Mary write the equation $${0.5(x+8)=6.50}$$ to represent the situation, where x represents the number of ounces of M&Ms.
Do you agree with either Kevita or Mary? Why? Finish solving the problem to find out how many ounces of M&Ms Kevita put in her bag of candy.
