Answer:
N equals to 749 newborn insects.
Explanation:
We have the following to calculate the population of newborn insects.
N = rl - bl2
In this equation we need to replace the values we know that are:
l = 500
r = 1.5
b = 0.0015
Whn we replace the values we have:
N = (1.5)(500) - (0.0015)(500)(2) <em>Now we just do the operations</em>
N = 750 - (0.0015)(1000)
N = 750 - 1.5
N = 748.5 <em>When we roung the nearest whole number we get</em>
N = 749
There were 749 new born insects that are represented by N.
