1. A community experiences linear population growth at a yearly rate of 3%. The populationin 2000 was 27,500; what was the population in 1985?Formula =i=n =Amt. =2. Alan purchased a jeep 20 years ago; today it is worth $500. The jeep depreciatesat an annual rate of 10%, compounded annually; how much did Alan pay for the jeep?Formula =n =Amt. =i=3. Alicia invests $10,000 into a mutual fund that experiences linear grow at an annualinterest rate of 7%. What is the value of her investment in 120 months?Formula =i=n =Amt. =4. A community's population increases monthly as a product of its current population and theperiodic growth rate (yearly rate is 3%). The population in 2000 was 27,500; what was thepopulation in 1990?Formula =i=Amt. =5. Jay deposits $500 into an investment account having a 7% annual rate of interest. Interest isadded at the time Jay closes his account (120 months from the time of his deposit) and is based onthe amount he deposited. What is the value of the account at closing?Formula =i=n =Amt. =1. A = P(1 + in) 2. P=3. A=P(1 + i) 4. P=-5. A=R[(1 + i)ª − 1]i6. R=Ai(1+i)n-17. A =R [¹ − (1 + i)-^]i8.
