Explain the process, using complete sentences, how to solve for the price of popcorn and the price of a drink.
Answer: 
Step-by-step explanation:
To find sin(60), you need to know the unit circle. Sin(60) is the same as sin(π/3). On the unit circle, sin(π/3) is √3/2. We know this because the coordinates are (cos, sin). Sin is the y coordinate.
Answer:
3x + 4y = 833
6x + 4y = 1058
II - I
3x = 225 --> x = 75
3*75 + 4y = 833 --> y = 152
