System of Three Equations in Word Problem - from 7.1
The Wittenberger Movie Showings sells two sizes of popcorn, a 1-gallon bucket and a 2-gallon bucket. Due to school policy, they must make at least twice as many 2-gallon buckets as 1-gallon buckets, In addition, the total number of buckets of popcorn made during a single workday cannot exceed 1800 buckets. The company makes $2 profit for each 1-gallon bucket sold, and they make $3 profit for each 2-gallon bucket of popcorn sold. The company would like to maximize their daily profit.
Let x = number of 1-gallon buckets made, y = number of 2-gallon buckets made.
Formulate objective function and constrains.
