A supermarket has bags of red grapes for 22.96 for 7 bags They also had bags of green grapes priced 9.60 for 3 bags

Which type was most expensive?

The bag of red grapes costs more.

Step-by-step explanation:

We can do proportions.

A supermarket has bags of red grapes for 22.96 for 7 bags:

For one bag of red grapes, its costs $3.28.

They also had bags of green grapes priced 9.60 for 3 bags:

One bag of green grapes costs $3.20.

The bag of red grapes costs more.

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
