Consider the following situation: A concession stand sells popcorn, soda, and candy. On a Saturday night, they sold a total of 434 items. The popcorn costs $1.00, the soda costs $1.25, and the candy costs $0.50. They made a total revenue that night of $445. They sold twice as many popcorns as they did candy. Set up, but do not solve, a system of 3 linear equations that model this situation. Again, you do not need to solve it. Type it in as best you can below.
