The population of a town can be represented by the formula P (t) = 541 + 350, where P(t) represents the population, in thousands, and t represents the time, in
years, since 1970 (note: t = 0 for 1970).
A) what are t values when it is 1985 and 1990. B) what is p(t), when t=25? Explain the meaning in words.

part A) see the explanation

part B) The population in 25 years since 1970 will be one million seven hundred thousand people (1,700,000)

Step-by-step explanation:

The correct equation is

Part A) what are t values when it is 1985 and 1990.

we have

This is the linear equation in slope intercept form

where

P(t) ----> is the population, in thousands

t ---->  the time, in  years, since 1970

Remember that

t = 0 for 1970

so

For the year 1985

For the year 1990

Part B) what is p(t), when t=25?

For t=25 years

substitute the value of t in the linear equation

Remember that the population is in thousands

That means

The population in 25 years since 1970 will be one million seven hundred thousand people (1,700,000)

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
