Astore has a 20% off sale on pants. with this discount, the price of one pair of pants before tax is $15.20. what was the original price of the pants?

$19

Step-by-step explanation:

Because we know that $15.20 is 20% off, that means $15.20 represents 80% of the original price. We can find how much 100%, the original cost, is if we found how much 1% costs and multiply that by 100. To find how much 1% costs, you would do 15.20/80 which is 0.19. Then, multiply 0.19 by 100. This results in the original price being $19.

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.
