Answer:
25% increase
Explanation:
To find percentage increase or decrease, use this equation:
{ [ ( Final ) - ( Initial ) ] / ( Initial ) } * 100
In this problem, 4 is the initial weight and 5 is the final weight. Now, let's plug these values into the problem to solve for percentage increase in the puppy's weight.
[ ( 5 - 4 ) / 4 ] * 100
[ 1 / 4 ] * 100
25%
So, the puppy's weight increased by 25% in three months.
