Question

Colin's puppy, Squeeker, weighed 1.5 pounds at his first vet visit. When Squeeker was a year old, he weighed 7.5 pounds. What percent did Squeeker's weight increase between the two visits? *

Answer 1

Squeeker initial weight is 1.5

After a year, Squeeker new weight is 7.5

`\begin{gathered} \text{percentage increase =}\frac{change\text{ in weight }}{\text{ intial weight}}\text{ }*\text{ 100 \%} \\ \text{ change in weight= new weight - initial weight = 7.5 - 1.5 =6.0} \end{gathered}`
`\begin{gathered} \text{percentage increase = }(6.0)/(1.5)\text{ }*\text{ 100 \%} \\ =\text{ 4}*\text{ 100\% = 400\%} \end{gathered}`
