$2.55

Step-by-step explanation:

He Sale flyer for cereal at a local grocery store states: Cereal 3 for $7.65 or 1 for $2.69.

How much is the unit price if you buy using the 3-box deal?

The unit price for the 3 box deal is :

3 boxes = $7.65

1 box = $x

Cross Multiply

3 × x = 1 × $7.65

3x = $7.65

x = $7.65/3

x = $2.55

The unit price for the 3 box deal is $2.55

the correct answer is 828.07

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
