Mrs. wise bought 3 lb of apples at $4 per lb. the next day, apples were on sale for “20% off” so she bought another 5 lb. what was the average price for all the apples she bought?

18

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.
