Last month, when Joe took his puppy to the veterinarian, the puppy weighed 4.5 pounds. This month, the puppy weighed 6.75 pounds. What is the percentage increase of the weight of the puppy?
To find the percentage increase in weight, we need to calculate the difference between the two weights and then divide that difference by the original weight. Finally, we multiply that quotient by 100 to express the result as a percentage.
The difference in weight is 6.75 - 4.5 = 2.25 pounds.
The original weight is 4.5 pounds.
The quotient is 2.25 / 4.5 = 0.5.
Multiplying by 100 gives us a percentage result of 50%.
Therefore, the weight of Joe's puppy increased by 50%.
