  • 2 Make a graph to show each person's donations. Use the same coordinate grid for all three graphs.

    A coordinate grid titled “Charity Donations” has an x-axis labeled “Number of Weeks” from 0 to 20 in intervals of 1 and a y-axis labeled “Total Donation (dollars)” from 0 to 65 in intervals of 5.

    • a. Who will be the first to donate a total of $30?

    • b. How many weeks will it take Vince to reach the $30 goal? Marta? Paula?

    • c. If Vince, Marta, and Paula continue making donations at the same rate, how much will each person have donated at the end of 1 year? (Reminder: There are 52 weeks in a year.)
