PETS Let $d(t)$ be the number of dogs in the United States in year $t,$ and let $c(t)$ be the number of cats in the United States in year $t,$ where $t=0$ corresponds to 2000
(a) Find the function $p(t)$ that represents the total number of dogs and cats in the United States. (b) Interpret the value of $p(5)$
(c) Let $n(t)$ represent the population of the United States in year $t,$ where $t=0$ corresponds to 2000 . Find and interpret
$h(t)=\frac{p(t)}{n(t)}$
