Answer:
If inflation were 5%, the value of the call in 50 years would be $ 57.33; while if inflation were 10% the value of the call would be $ 586.95.
Step-by-step explanation:
Given that a telephone call to London that currently would cost $ 5, to determine, if the real price of telephone calls does not change in the future, how much will it cost you to make a call to London in 50 years if the inflation rate is 5% and if inflation is 10%, the following calculations must be made:
5 x 1.05 ^ 50 = X
5 x 11.4674 = X
57.33 = X
5 x 1.1 ^ 50 = X
5 x 117.39 = X
586.95 = X
Therefore, if inflation were 5%, the value of the call in 50 years would be $ 57.33; while if inflation were 10% the value of the call would be $ 586.95.
