The cost of 5 folders and 1 pen is $8.25. What is the cost of each item? Include appropriate units in your answer. 11) While bored, the cashier at a convenience store counts the coins in the coin tray by the register. He finds that there are 22 pennies and dimes, totaling 58 cents. How many pennies did he count? Honors Review Johnson's Produce is purchasing fertilizer with two nutrients: Nitrogen and Phosphorus. They need at least 90 pounds of phosphorus, and state law says they can buy no more than 180 pounds of nitrogen in a single order. Their supplier has two brands of fertilizer available. Brand X has four pounds of nitrogen and one pound of phosphorus per bag. Brand Y has one pound of each nutrient. a) Write a system of inequalities that models the situation above. b) If Johnson’s Produce got 15 bags of Brand X, between how many bags of Brand Y could they legally purchase and still meet their minimum phosphorus need? Number of bags of Brand Y c) Graph the system on the axes below. Number of bags of Brand X d) What is the largest number of bags of Brand X Johnson’s Produce could buy to meet their need and still abide by the law?
