You start out with $20 and then spend money in a store where every item is $3. Y = -3x + 20. Use your graph for problem to predict the answer. What is the largest number of items you can buy?

    With that equation, wouldn't it be simple to quickly finish the question by following the last 2 sentences?

    You only have $20. Your inequality would be 3x has to be less than or equal to 20. You could buy 6 items. You would have 2 dollars leftover.
