1. A car priced at $25,329 is financed with a simple interest rate of 4.25% for 5 years with no down payment. Payments
of $511.86 are made each month. Another car priced at $22.464 is financed with a simple interest rate of 3.78% for 5
years with a down payment of $2,500. Payments of $395.62 are made each month.
a. For each loan, generate a table, graph, and equation that can be used to represent the balance after the down
payment, if applicable, and the first 12 months of payments. The tables should represent the number of months
in terms of x and the balance of the loan after each month's payment in terms of y.
b. Determine the rate of change, or slope, of each line and state the y-intercepts.
c. Using your generated graph for the first situation, describe how the unit rate of the amount of money paid
monthly is related to the slope of the line.
d. Determine if each relationship represented in the table, graph, and equation represents a proportional or non-
proportional situation
e. Use a set of ordered pairs, table, mapping, or graph to determine if each relationship represents a function.
