Math: Inventory ?
A store sells two models of laptop
computers. The store stocks at least twice as many units of model A as of model B. The costs to the store for the two models are $800 and $1200, respectively. The management does not want more than $20,000 in computer inventory at any one time, and it wants at least four model A laptop computers and two model B laptop computers in inventory at all times. Write and
graph a system of inequalities that describes all possible inventory levels.

Let x be the number of units of model A in inventory
Let y be the number of units of model B in inventory
The info in the question leads to four inequalities:
x ≥ 2y ….. 'store stocks at least twice as many units of model A as of model B'
800x + 1200y ≤ 20,000
x ≥ 4
y ≥ 2
The central triangular region where all the inequality graphs overlap is the solution set.
