1) which equation could be used to estimate the population of oak city in 10 years?
a) y = 48000(1.024)10
b) y = 48000(0.024)10
c) y = 48000(1.24)10
d) y = 48000(10.24)10

2) which equation could be used to estimate johnson city's population in 5 years?
a) y = 82000(1.983)5
b) y = 82000(0.983)5
c) y = 82000(−0.017)5
d) y = 82000(98.3)5

1) A

2) B

Step-by-step explanation:

For this problem we use exponential growth formulas

if the population increases when t increases

If the population decreases when t increases

Where and is the population as a function of time, is the initial population, r is the growth rate, t is the time in years.

1) In this situation we have that , the growth is 2.4%, then and and the equation is:

-------- Option A)

2) In this situation we have that , the decrease is 1.7%, then and and the equation is:

-------- Option B)
