A pair of designer sneakers was purchased for $150. Since they were purchased, their price has increased by 15%. What is the new price?

$172.50

Step-by-step explanation:

150 increase 15% =

150 × (1 + 15%) = 150 × (1 + 0.15) = 172.5

$172.50

Step-by-step explanation:

You have to multiply 150 by 1.15 because that is 150 plus 15% of itself.

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.
