A coffee retailer sells two types of coffee beans, the Arabica and Robusta. The Arabica coffee bean costs $9 per pound and the Robusta costs $7 per pound. Find a possible amount of Arabica and Robusta that can be mixed together to yield a quantity of coffee beans costing less than $25.50. Graph the inequality and show the possible solution on the graph.

Write the inequality that represents the possible amounts of each type of coffee.
