uppose you want to buy some external hard drives for data storage. - You can buy up to 13 small external hard drives. - You can buy up to 8 large external hard drives, but you need at least 4 of them. - You must get enough small and/or large external hard drives to hold at least 1500 total ter (TB) of data. - Each small external hard drive holds 90TB - Each large external hard drive holds 120 TB. - A small external hard drive costs $40. - A large external hard drive costs $50. How many small and large external hard drives should buy to minimize your cost? 1) Define your variables Let x= number of small external hard drives purchased Let y= number of large external hard drives purchased. 2) Define your constraints (and graph on GeoGebra. Label axes appropriately). 3) Define your objective function (and enter into GeoGebra). 4) Find the feasible region (be sure to clearly display this region on GeoGebra). a. Using the polygon tool is a nice way to do this. 5) Find a point inside the feasible region that represents the quantity of each size purchased
