Question
A manufacturer of pop-up tents makes 2-person tents and 4-person tents. The profit from the sale of these tents is given by
P(T,F) = 82T + 162F -0.15TF -0.27² -0.3F² - 9000 dollars
when $T is the price of the two-person tent and $F is the price of 4-person tent.
Check: P(40,60) = 2240
The P = $10,000 contour curve has been sketched for 75 ≤ T ≤ 200 and 90 ≤ F≤ 130 and a tangent line has been constructed at the point (100,113.25).
