Question 861770: This requires 3 sets of answers and I am totally lost with all. I hope you can help and explain to me in the simplest way how you achieved the answers.
Thank you in advance.
Formulate the situation as a system of inequalities. (Let x represent the number of goats the farmer can raise and y represent the number of llamas.)
A rancher raises goats and llamas on his 400-acre ranch. Each goat needs 2 acres of land and requires $100 of veterinary care per year, while each llama needs 5 acres of land and requires $80 of veterinary care per year. If the rancher can afford no more than $13,200 for veterinary care this year, how many of each animal can he raise?
_________(land requirements)
_________(veterinary requirements)
x> 0, y > 0
Find the vertices. (Order your answers from smallest to largest x, then from smallest to largest y.)
Sketch the feasible region.

Hi,
2x + 5y = 400 |mulitplying thru by -50 and adding to 2nd EQ to eliminate x
100x + 80y = 13,200
-170y = -6800
y = 40 Lamas and 140 goats
