Solve the Problem $\mathrm { F } _ { 1 }$

Solve the problem.
-A certain area of forest is populated by two species of animals, which scientists refer to as A and B for simplicity. The forest supplies two kinds of food, referred to as $\mathrm { F } _ { 1 }$ and $\mathrm { F } _ { 2 }$ . For one year, species A requires $1.4$ units of $\mathrm { F } _ { 1 }$ and $0.95$ units of $\mathrm { F } _ { 2 }$ . Species $\mathrm { B }$ requires $2.1$ units of $\mathrm { F } _ { 1 }$ and $1.7$ units of $\mathrm { F } _ { 2 }$ . The forest can normally supply at most 938 units of $\mathrm { F } _ { 1 }$ and 492 units of $\mathrm { F } _ { 2 }$ per year. What is the maximum total number of these animals that the forest can support?

A) 209 animals
B) 351 animals
C) 517 animals
D) 1021 animals
