Finish the team worksheet activity from last week. You'll be given 6 cards with tables. Determine whether each table is proportional (P) or not proportional (NP) and copy the table to the indicated chart on the worksheet. Then graph the points from the table and connect the dots to show why the graph is or is not a proportion. Finally, if the table does show a proportion, give the equation for the proportion: the form of the equation is y=ax where a is the constant of proportionality. If the table does not show a proportion, no equation is needed.

Practice calculating simple interest as follows:
Find the total value of the investment after the time given. Remember to convert percentages to decimals, e.g., 10% = 0.10.
- $40,000 at 16% simple interest for 3 years.
- $1,160 at 11% simple interest for 3 years.
- $5,500 at 13% simple interest for 7 years.
- $560 at 12% simple interest for 2 years.
- $56,000 at 15% simple interest for 4 years.
- $300 at 6% simple interest for 6 years.
