Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.

Drag each equation to the correct location on the table. for each equation, determine the number of solutions and place on the appropriate field in the table.
