A sporting goods store uses a markup of 87.5% for baseball bats. What is the price the store should display for a baseball bat with an original cost of $40? Use words to complete the equation you should use to find the amount of the markup.
= percent × .

Because the store marks up the original cost, the price will decrease / increase. The percent change is %.

Write an equation that gives the retail price y of a bat with an original cost of x.

y =1x + x = x

To find the price that the store should display, substitute for x in the equation in Part C. The store should display a price of $ .

Describe the symmetry of the figure. identify lines of symmetry, if any. find the angle and the order of any rotational symmetry.

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.

Write the slope intercept equation for line ab.
