There’s a dress for sale for $70 dollars but the store is selling it for $20 dollars. what is the the percent decrease in in price?

I'm thinking 50%? But i am probabl wrong.

If you take 50/70 and multiply by 100 that is the % mark down in price.

That's about a 71% markdown.

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.

the answer is 99.
