Solve the problem of exponential growth. in 1985 an antique automobile club had 23,000 members. since then its membership has grown at an average rate of 5% per year. assuming this trend continues, how many members will there be in 2020? round to the nearest thousand.

Step-by-step explanation:

In this problem we have an exponential function of the form

where

a is the initial value

b is the base

The base is equal to

b=1+r

r is the average rate

In this problem we have

a=23,000 members

r=5%=5/100=0.05

b=1+0.05=1.05

substitute

x ----> is the number of years since 1985

How many members will there be in 2020?

x=2020-1985=35 years

substitute in the function

Round to the nearest thousand

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
