Question

As a fundraiser, Student Council sold two types of candy: lollipops for 40 cents each and chocolate bars for 75 cents each. On Monday, the students sold 150 candies and raised $74. How many lollipops did they sell?

Answer 1

L + C = 150 ... 75 L + 75 C = 150 * 75

40 L + 75 C = 7400

subtract the equations to eliminate C and solve for L
