Answer to Problem 38P

The better option is B which would save $8.30M

Explanation of Solution

Given information:

  First CostO & M Cost/yearSalvageLifeA$14M$3.5M$2M8 yearsB22M3M7.5M16 years

Formula used:

  PWA=14A( ( 1+i )N1i ( 1+i )N)+F(1 ( 1+i )N) A( ( 1+i )N1i ( 1+i )N)+ F(1 ( 1+i )N)

  PWB=22 A( ( 1+i )N1i ( 1+i )N)+ F(1 ( 1+i )N)

PW represents Present Worth

A is end of period cash receipt or disbursement in a uniform series continuing for “n” periods

F is Future sum of money at the end of the nth interest period, which is equivalent to “P” with interest rate “i”.

P isPresent sum of money

i is Effective interest rate per interest period

N is Number of interest period

Calculation:

By using the above-mentionedformulas, Present Worth is calculated.

Present Worth for choice A

  PWA    =( 143.5( ( 1+.18 ) 8 1 .18 ( 1+.18 ) 8 )+( 214 )( 1 ( 1+.18 ) 8 )  3.5( ( 1+.18 ) 8 1 .18 ( 1+.18 ) 8 )+2( 1 ( 1+.18 ) 8 ))=143.5(4.08)12(0.27)3.5(4.08)+2(0.27)=$45.26M

The above formula gives the Present Worth for choice A of $45.26M

Present Worth for choice B

  PWB     =223( ( 1+.18 ) 16 1 .18 ( 1+.18 ) 16 )+7.5(1 ( 1+.18 ) 16 )=143(5.16)+7.5(0.07)=$36.96M

The above formula gives the Present Worth for choice Bof $36.96

Therefore, the best choice between A & B is B as it saves $8.30M
