The correct equation to represent when the two popcorn machines will have the same amount of popcorn left is:
120 - 7x = 150 - 9x ; x = 15
Movie Theatre A has a popcorn machine with a 120-gallon capacity. It sells 7 gallons of popcorn per hour. Movie Theatre B has a popcorn machine with a
150-gallon capacity. It sells 9 gallons of popcorn per hour. Write and solve an equation to show when the two popcorn machines will have the same amount of popcorn left. (1 point)
• 120х — 7 = 150х — 9 ; х = 15
• 120 - 7х = 150 - 9x; x = 15
• 120 - 7х = 150 - 9х ; x = 10
• 120 + 7x = 150 + 9x; x = -15
