Question

Nicole owns and operates two restaurants. The revenue of the first restaurant at time t is f(t) dollars, and the revenue of the second restaurant at time t is g(t) dollars. What does the function F(t) = f(t) + g(t) represent?

Answer 1

Answer:

$F(t)=f(t)+g(t)$ represents the TOTAL revenue at time $t$.

Explanation:

$f(t)$ is the revenue at the time $t$ at the first restaurant.

$g(t)$ is the revenue at the time $t$ at the second restaurant.

If we want to know the TOTAL revenue at the time $t$, we would sum these quantities:

TOTAL revenue = $f(t)+g(t)$

So $F(t)=f(t)+g(t)$ represents the TOTAL revenue at time $t$.
