Question

Alligator 1 initial weight is 4 lbs. the rate of growth is 2 lbs. per month. Alligator 2 initial weight is 8 lbs. the rate of growth is 1 lb per month. After how many months will both alligators weigh the same amount?

Answer 1

• 4 months

Explanation:

Let the number of months be x

Alligator 1 weight = 4 + 2x

Alligator 2 weight = 8 + x

• 4 + 2x = 8 + x
• 2x - x = 8 - 4
• x = 4

The answer is 4 months
