Question

kelby has several pets. she has b birds, c cats, and f frogs. the expression b + (c + f) represents the total number of pets kelby has. what does c + f represent in this context? choose 1 answer: the total number of cold - blooded pets the total number of warm - blooded pets the total number of pets with 2 legs the total number of pets with 4 legs

Explanation:

Birds are warm - blooded animals with 2 legs. Cats are warm - blooded animals with 4 legs. Frogs are cold - blooded animals with 4 legs.
Since \(C\) represents the number of cats (warm - blooded, 4 legs) and \(F\) represents the number of frogs (cold - blooded, 4 legs), \(C + F\) is the sum of the number of cats and frogs. Both cats and frogs have 4 legs.

Answer:

D. The total number of pets with 4 legs
