Sally starts a lemonade stand. She has a startup cost of $20 dollars and each glass of lemonade she sells costs her $1.25 to make. She charges
$2.50 for a glass of lemonade. How many glasses of lemonade does she
need to sell for her total costs to be exactly equal to her revenue (the
money she makes from selling lemonade).

Sally will need to sell 8 glasses of lemonade

Step-by-step explanation:

Very Simple, you just need to do 20 divided by 2.50 and there is your answer

Hope this helps :)

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.

unless if u could do my questions, if not i wouldn't want to
