How much would you have to invest today in the bank at an interest rate of 10% to have an annuity of $5600 per year for 7 years, with nothing left in the bank at the end of the 7 years? (round to nearest dollar)

PV = $27,263.15

It will be needed to deposit the lump sum of $27,263.15

Explanation:

The question is asking for how much will you need to deposit in a lump sum  today to withdraw for seven years the sum of $5,600 with an interest rate of 10%

In other words it is asking us for the preset value of an annuity of $5,600 with interest of 10%

Using the present value of an annuity formula of $1 we can solve for the present value of that annuity, which is the amount needed to generate this annuity

We post our knows value and solve it:

PV = $27,263.15

Security B

Explanation:

The risk of an asset is measured by beta

Market beta is measured by 1. Securities that move more than the market have a beta greater than 1 .

Securities that moves less than the market have a beta less than 1

The beta of security A is less than that of security B. Thus, security B is more risky
