Question

Victoria and Javier are collecting aluminum for a community service project. Victoria previously collected 56 pounds and is collecting at a rate of 8 pounds per hour this weekend. Javier collected 16 pounds earlier and Is now collecting at a rate of 12 pounds per hour. How many hours must pass (x) before the two students have collected the same amount of aluminum (y)?​

Answer 1

• 10 hours

Explanation:

Victoria collects:

• 8x + 56

Javier collects:

• 12x + 16

They get same amount:

• 8x + 56 = 12x + 16
• 12x - 8x = 56 - 16
• 4x = 40
• x = 10
