In what time will $500 give $50 interest at the rate of 5% per year

Using simple interest formula:

As per the given statement:

$500 give $50 interest at the rate of 5% per year.

To find the time T;

Here, P = $500 , I = $50 , R = 5%

Substitute these given values in the given formula we have;

Simplify:

Divide both sides by 25 we get;

T = 2 years

Therefore, in 2 years will $500 give $50 interest at the rate of 5% per year

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
