For a given week, Nahla's Coffee House has available 1792 grams of A grade coffee and 1600 grams of B grade coffee. These are blended into 16-gram packages as follows: an economy blend that contains 4 grams of A grade coffee and 10 grams of B grade coffee, and a superior blend that contains 8 grams of A grade coffee and 2 grams of B grade coffee. (The remainder of each blend is made of filler ingredients.) There is a $1 profit on each economy blend package sold and a $3 profit on each superior blend package sold. Assuming that the coffee house is able to sell as many blends as it makes, how many packages of each blend should it make to maximize its profit for the week? Note that the ALEKS graphing calculator can be used to make computations easier. Economy blend: | package(s) Superior blend: package(s)

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
