6. using table 11-2 from your text, calculate the present value (principal) and the compound interest given: compound amount = $1,250 term of investment = 6 years nominal rate = 6% interest is compounded semiannually

The Principal is $877.19    And  Compound Interest is $372.81  

Step-by-step explanation:

Given as :

Amount after investment = $1250

The time period of investment = 6 years

The nominal rate = 6% compounded semiannually

Let the principal = P

From compounded method

Amount = Principal ×

Or, $1250 = P ×

Or, $1250 = P ×

Or, $1250 = P × 1.425

∴   P =

I.e P = $877.19  

So , Principal = $877.19

Now, Compound Interest = Amount - Principal

                                          = $1250 - $877.19

Or,                                CI  = $372.81

Hence The Principal is $877.19    And  Compound Interest is $372.81  Answer

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
