Solve the problem.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 $44 in 1944. 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.
A. P(t) = P0e-0.037t
B. P(t) = P0e-0.03t
C. P(t) = P0e-0.032t
D. P(t) = P0e-0.034t
