Jamal and Aunt Eunice Task

Jamal wants to buy a Sony PlayStation 2 with accessories. The entire package costs $234.10. Jamal has already saved $39.

Every Saturday night Jamal’s Aunt Eunice comes over for dinner. Aunt Eunice has no children and is always interested in what Jamal is doing. He told her about the PlayStation and she made him a deal. Since she believes that saving money for the things that you want is a virtue, she will match every dollar Jamal saves 3 to 1 beginning at that moment. Aunt Eunice will take him, after Saturday night dinner, to buy the PlayStation.

Jamal figures that he can save $4 per week. The Saturday that Aunt Eunice came for dinner was April 1st. When can Jamal buy his PlayStation?

1. Create a table to determine how long it will take Jamal to save his money for the PlayStation.

2. Represent your table by drawing a graph.

3. Would it make sense to connect the points on your graph? Why or why not?
