We Modeled Populations of Aphids and Ladybugs with a Lotka-Volterra $\frac { d L } { d t } = - 0.6 L + 0.0005 \mathrm { AL }$

question 3

Multiple Choice

We modeled populations of aphids and ladybugs with a Lotka-Volterra system.Suppose we modify those equations as follows: \) \frac { d A } { d t } = 2 A ( 1 - 0.0005 A ) - 0.01 A L\) $\frac { d L } { d t } = - 0.6 L + 0.0005 \mathrm { AL }$
Find the equilibrium solution.

• A) \(A = 3200 , L = 110\)
• B) \(A = 4700 , L = 90\)
• C) \(A = 3700 , L = 120\)
• D) \(A = 1200 , L = 80\)
• E) \(A = 1500 , L = 100\)
