I need help finding an eqaution for this. Thank you in advanced

Formula:

Normal Price:

Step-by-step explanation:

First, you have to find the current price of one cookie.

Since 7 cookies cost $2.80, then the price for one sale price cookie would cost

Then you would have to add the $0.75 to the sale price to get the normal price.

The normal price of a cookie would be $1.15.

The formula to get that answer would be:

Hope this helps!

the answer is 288..

hope this

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
