You have a place in the mountains of New$-$Mexico. Condition of the range is poor. Although the terrain is rugged, water is well distributed. You want to graze this range for a year. Production of the key forage species averages about $350$ lb$./$ac$/$year$.$ The total area is $35,000$ ac$.$ slope on this range is as follows: $20\%$ of the range has $0$ to $10\%$ slope. $30\%$ has $11$ to $30\%$ slope, $10\%$ has $31$ to $60\%$ slope, and $40\%$ has over $60\%$ slope.

Question $2$: If sheep were substituted for cattle, how many sheep can you have in your base herd.

Question $3$: If this range were used for only $2$ months with yearlings, how many yearlings can you run?
