Method A assumes simple interest over final fractional periods, while Method B assumes simple discount over final fractional periods. The annual effective rate of interest is 20%. Find the ratio of the present value of a payment to be made in 1.5 years computed under method A to that computed under Method B.

The answer is "1.1"

Explanation:

In the case of a single Interest, the principal value is determined as follows:

In case of discount:

Let income amount = 100, time = 1.5 years, and rate =20 %.

Formula:

A = P(1+rt)  

A =P+I

by putting vale in the above formula we get the value that is = 76.92, thus method A will give 76.92  value.

If we calculate discount then the formula is:

P = M(1-rt)

M = 100  rate and time is same as above.

Thus Method B will give the value that is 70  

calculating ratio value:

due to the changes the federal reserve is making the unused reserves will impact the economy by them facing inflation. inflation is definfed as the increase in pricing of a good or service but the decline of the value of money used for purchasing those items. when the economy has a high inflation rate, they are subject to money loss and hurt on the economy.
