A local store charges $8 to rent a video game. You must be a member to rent from the store, but the membership is free. Another local store, charges $3 to rent a video game, but the membership in the club is $50 a year.

Find the number of rentals for which the two plans would cost the same.

10 rentals

Step-by-step explanation:

One store: $8 per rental + $0 for membership fee

Other store: $3 per rental + $50 for membership fee

Let x = number of rentals.

8x = 3x + 50

5x = 50

x = 10

10 rentals

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
