Suppose that the number of newborns (n) in an insect population can be predicted from the number of adult insects (i) according to the following equation, where r and b are variables related to the rates of population growth: n=ri−bi2. calculate n if r=1.5, b=0.0015, and i=500. rounding to the nearest whole number, n equals which of the following?

a. 1880
b. 375
c. 188
d. 749

d. 749

Explanation:

To calculate the number of newborns (N) in an insect population using the equation N=rI−bI2, where r and b are variables, given that:

r=1.5, b=0.0015, and number of adult insects (I) = 500.

Solve for N in the equation by substituting for r, b and I with the values given.

Number of newborns (N) = rI−bI2  

                                          = (1.5 × 500) - (0.0015 × 500 × 2)

                                          = 750 - 1.5

                                       N = 748.5  

Rounding up to the nearest whole number, N = 749

749 newborn insects were represented by N
