Exercise Module Performance Task Page 122

We can choose between the three different season-pass options shown in table below. We are asked to find the least expensive option from there.

Plan A	Plan B	Plan C
One payment of $500$.	$\$80$ down payment and $6$ montly payments of $\$75.$	$\$60$ down payment and $11$ montly payments of $\$45.$

In order to compare them, we will find the total cost for each option. We know that Plan A is a single payment of $\$500.$ Then, we can move to Plan B. It consists of an initial payment of $\$80$ plus $6$ monthly payments of $\$75.$ We can write this information as a function rule using $m$ as the number of months.
