3. Target is selling two popular toys this year for kids. Toy x is a Power Treads and toy y is an America Girl Doll. Target pays $8 each for the Power Treads and $14 each for the America Girl
Doll. One unit of Power Treads yields a profit of $2 while an America Girl Doll yields a profit of
$3. Target estimates that no more than 2,000 toys will be sold-every month and does not plan
to invest more than $20,000 in inventory for these toys. How many units of each type of toys
should be stocked in order to maximize the monthly total profit?
What are the vertices? What are the constraints? What is the profit equation?
