The answer is R=0.053707443....
Round to the nearest decimal place as it asks for
i hope this helps :)
In money if you have £6.25 it is easier to write it in decimals
If you are measuring something e.g. 10.3cm long no one writes it 10 3/10 cm
There are 2,000 fifties in one hundred thousand
The product of 379 and 8 is 3,032.
It's between (any number less than 3,032) and (any number greater than 3,032).
I guess if this is an <em>estimation </em>exercise, you could say that it's between
(8 x 300) and (8 x 400), or 2,400 and 3,200.
I believe the answer should be approximately 6,147 because you would plug into the equation y=20,000(.95)^t, where t=23.
