After what amount of time will  the salvage value be $639?
◦ After 10.6 years
◦ After 8.6 years

Question 2

A consumer group in one city compares the costs of goods and services in that city over various years, and uses 1970 as a base.  The same goods and services that cost $100 in 1970 cost $42 in 1941.  Assuming the exponential-decay model, find the value of k, and write the equation.   Round the value of k to the nearest thousandth. Let t be the number of years before 1970.
◦ P(t) = P0e-0.028t
◦ P(t) = P0e-0.035t
◦ P(t) = P0e-0.03t
◦ P(t) = P0e-0.032t
