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 :

Squeeker initial weight is 1.5

After a year, Squeeker new weight is 7.5

[tex]\begin{gathered} \text{percentage increase =}\frac{change\text{ in weight }}{\text{ intial weight}}\text{ }\times\text{ 100 \%} \\ \text{ change in weight= new weight - initial weight = 7.5 - 1.5 =6.0} \end{gathered}[/tex][tex]\begin{gathered} \text{percentage increase = }\frac{6.0}{1.5}\text{ }\times\text{ 100 \%} \\ =\text{ 4}\times\text{ 100\% = 400\%} \end{gathered}[/tex]
