Movie Theatre A has a popcorn machine with a 100-gallon capacity, and sells 3 gallons of popcorn per hour. Movie Theatre B has a popcorn machine with a
150-gallon capacity, and sells 5 gallons of popcorn per hour. Write an equation to show when the two popcorn machines will have the same amount of popcorn left. Use x as your variable. (1 point)
• 100 + 3x = 150 + 5x
• 3х — 100 = 5х — 150
• 150 + 3x = 100 + 5x
• 100 — 3х = 150 — 5x
1 answer
• 100 + 3x = 150 + 5x
