Question

A young channel catfish weighs about 0.2 pounds. During the next 8 weeks, its weight increases by about 29% each week.

Predict what the weight would be after 7 weeks.

Answer 1

the weight of the catfish after 7 weeks would be approximately 1.195 pounds.

Explanation:

After each week, the weight of the catfish increases by 29%, which is equivalent to multiplying the weight by 1.29.

Let's calculate the weight of the catfish after 7 weeks:

Week 1: 0.2 pounds x 1.29 = 0.258 pounds

Week 2: 0.258 pounds x 1.29 = 0.333 pounds

Week 3: 0.333 pounds x 1.29 = 0.430 pounds

Week 4: 0.430 pounds x 1.29 = 0.555 pounds

Week 5: 0.555 pounds x 1.29 = 0.717 pounds

Week 6: 0.717 pounds x 1.29 = 0.926 pounds

Week 7: 0.926 pounds x 1.29 = 1.195 pounds

Therefore, the weight of the catfish after 7 weeks would be approximately 1.195 pounds.
