Brenda likes bagels and sparkling water. The bagels cost $2 each and sparkling water cost
$1.25 per bottle. There is a special promotion for sparkling water that will last for one month. If
Brenda sends in the bottle tops from the sparkling water she drinks during the next month, she will
get a refund of $.25 for every bottlecap beyond the first 12 that she returns. For example, if she
returns 25 bottle caps, she will get back $3.25 = $.25(25 − 12). Brenda has $40 to spend on bagels
and sparkling water during the next month. Draw her budget line with sparkling water on the
horizontal axis and bagels on the vertical axis. Find the points where the budget line hits the axes
and the point where it has a kink. At each of these three points write down the quantities of each
good consumed.
