kelby has several pets. she has b, birds, c cats, and f frogs. in this expression b + (c+f) represents the total number of pets kelby has what does c+f represent in this context

The number of cats an frogs

Step-by-step explanation:

For some reason the equation has (c+f) grouped off from the rest, since in an equation the first step is to take care of things in the parentheses, first you must add the two together, and based on the description, you know that c is the number of cats and f is the number of frogs. Therefore adding them together would get the total number of cats and frogs.
