CPM Homework Help : CCA Problem 7-47

The leadership class at Mt. Heron High School is organizing a shoe drive. A local business has agreed to donate boxes to collect the shoes in. If each box can hold $20$ pairs of shoes, draw a step graph relating the number of shoes collected to the number of boxes needed for up to $200$ pairs of shoes.

Hint:

Label the x-axis 'Pairs of Shoes' and label the y-axis 'Boxes'.

Answer:

A step graph with x axis labeled as Pairs of Shoes scaled in twenties from 0 to 200 and y axis labeled as Boxes scaled in ones from 0 to 10. The first step is from open circle on (0, comma 1) to closed circle on (20, comma 1). The next step is from open circle on (20, comma 2) to closed circle on (40, comma 2). The steps continue in this pattern until the last point at (200, comma 10).
