Mary Magnolia a flower shop owner has her choice of 3 different floor sizes, 200 square feet, 500 square feet, and 100 square feet at a price of $1 per square feet.

If she has F square feet and sells Q bouquets a month, her variable costs will be Cv(Q)= Q²/ F per month

For each shop size (or just show one of them so I can understand the others!)

How do I determine the total average cost function, at what Q is average cost minimized, and at that Q, how much is average cost?

We don't use calculus in this course so how do you solve it algebraically or graphically?
