Find the rate of money collected per sweatshirt sold.

+20

Step-by-step explanation:

I added 20 dollars per sweatshirt. I wasn't sure if you wanted me to fill in the blanks or not, but :

5 sweat shirts is 100

8 is 160

and the 180 one is 9 sweatshirts

while the last one is 240.

The pattern makes sense in the context!!

I hope this makes sense!!

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
