# Algebra 1--how am I suppose to graph this?!

Jeff builds model train layouts. He has \$75 to spend on packages of miniature landscape items. He receives 6 free packages with each other. The number of packages that Jeff can buy is given by y = 75/x + 6, where x represents the cost of each package in dollars. Describe the reasonable domain and range value and graph the function.

1. plot it the way you plot any function! Pick some values of x and calculate y. Then plot the point at (x,y).

The curve will be smooth, but the only poi9nts that make sense in the real world are where x is a divisor of 75.

Your graph should look like this:
