Which function represents the population of Grennito tyears after 1992? Grennito had a population of 24,800 people in 1992 when a new factory opened. Since then, the population has grown at a steady rate of 4.7\% per year
Answer: Population of Grennito after t years (P) = 24800e^(0.047t)
Solution:
Population of Grennito in 1992 (A)= 24800
Growth rate (r) = 4.7%
= 4.7/100
= 0.047
Exponential growth is modeled by the formula
P = Ae^(rt)
P is the current or future population
A is the starting population = 195000
r = growth rate = 0.047
t = time in years (since 1992)
Population of Grennito after t years = 24800e^(0.047t)
Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram
