QUESTION 1
Solve the problem.
A city is growing at the rate of 0.4% annually. If there were 2,918,000 residents in the city in 1995, find how many (to the nearest ten-thousand) are
living in that city in 2000. Use y = 2,918,000(2.7) 0.004t.

Solve the problem.
( (1 + r)t+1-1
The formula S = A
models the value of a retirement account, where A = the number of dollars added to the retirement account each
mod
year, r= the annual interest rate, and S = the value of the retirement account after t years. If the interest rate is 6%, how much will the account be
worth after 10 years if $1600 is added each year? Round to the nearest whole number.

(1 + r) – 1
The formula S = A
models the value of a retirement account, where A = the number of dollars added to the retirement account each
year, r = the annual interest rate, and S = the value of the retirement account after t years. If the interest rate is 8%, how much will the account be
worth after 45 years if $2000 is added each year? Round to the nearest whole number.
