Question

Quizplus · Accepted Answer

To find the increase, we need to multiply the current population by the percentage increase in decimal form. 
20% as a decimal is 0.20 
75 million x 0.20 = 15 million 
To find the projected population, we add the increase to the current population. 
75 million + 15 million = 90 million 
Therefore, the best choice is C, with an increase of 15 million mosquitos and a projected population of 90 million mosquitos. To find the increase, we take 20% of the current population:
0.20 x 75 million = 15 million increase
To find the projected population, we add the increase to the current population:
75 million + 15 million = 90 million projected population
Choice C is the only one that matches these calculations.
