D. What will the marginal revenue be when the revenue is maximized. Why?
E. Find the instantaneous rate of change of revenue at 400 steam irons.

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

if the probability is 1/12, 75 people will receive a $25 gift card
