Dan needs to buy some pencils. Brand A has a pack of 12 pencils for $3.29. Brand B has a pack of 28 pencils for $8.99 . Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent.

First, you have to find the unit price for each brand by dividing the pack price by the number of pencils in each pack.

Brand A: $3.29/12= $0.27

Brand B: $8.99/28= $0.32

With this information, you can say that the brand that is the better buy based on the unit price is Brand A because it has a cheaper price per unit.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
