The price of dinner before sales tax and tip is $60.

Step-by-step explanation:

Let the price of before sales tax and tip be x.

The amount of tip is 20% of the price of dinner. So, the amount of tip is

The amount of sales tax is 11% of the price of dinner. So, the amount of sales tax is

Therefore the price of dinner before sales tax and tip is $60.

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
