Answer 2

The weight increased by 50% over 3 years:

increase = 50%

Current weight = 100 + 50 = 150%

Find the weight 3 years ago:

Current weight = 150%

Current weight = 45 pounds

150% = 45 pounds

1% = 45 ÷ 150

1% = 0.3 pound

1% = 0.3 pound

100% = 0.3 x 100

100% = 30 pounds

Answer: The dog was 30 pounds 3 years ago.
