Jamal is buying ingredients to make a large batch of granola to sell at a school fair. he buys 3.4 pounds of walnuts for $4.65 per pound and 2.1 pounds of cashews for $6.53 per pound. how much change will he receive if he pays with two $20 bills? he will receive

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.

1/800 is the right answer
