Question

A dog's weight increased by 50% in three years. by the end of the 3 years, the dog weighed 45 pounds. how much did the dog weigh three years ago?

Answer 1

Let, the weight before 3 years = x

Then, it would be: x * 150/100 = 45
x * 1.5 = 45
x = 45/1.5
x = 30

So, your final answer is 30 Pounds

Hope this helps!
