The projected population size in 2030 will be : ≈ 44159 
First step : determine the population growth rate 
Gr = change in population / time 
     = ( 1500 - 1100 ) / 1 year 
     = 400 = 36% 
<h3>Determine the projected population size </h3>
applying Malthus's population projection. 
 Pp = P₁ ( 1 + r )ⁿ
 where ; P₁ = 1500, r = 0.36 , n = ( 2030 - 2019 ) = 11 years 
Pp = 1500 ( 1 + 0.36 )¹¹
     = 1500 ( 29.439 ) 
     = 44158.5  ≈ 44159 
Hence we can conclude that the projected population size as at 2030 is 44159

Answer: C.) The actions of consumers in response to changes in price.
Explanation:
The Law of Demand states that as the price of a service/product decreases, the demand will increase and vice versa. Therefore, it doesn't necessarily related to the producer's response, but the consumer's. And since the consumer isn't producing, they are not in direct contact with the production costs. 
I hope this helped !
Good luck <3
