The freshmen class officers at Interlake High School ordered 1,200 fruit bars to sell as a fundraising project. They paid $0.30 per bar at the time the order was placed. They plan to sell the fruit bars at school games and concerts for $0.75 apiece. No returns of unsold bars are possible. a. If the freshman class sells 100 of the fruit bars, what is their profit?
b. How many bars does the freshmen class need to sell to “break-even” (make a profit of $0)?
c. Write an expression that shows how the project profit depends on the number of bars sold.

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.
