In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this question:

First year:
Amount of 2% interest, during 1 year.
So the interest earned is:
The total amount at the end of the first year is:

The interest earned is of:
The total amount is:
After two years, the investment is worth £8653.68 How much did Briony invest?
So
Brionny invested £8400.
Number 3 is 1:3 but I don't know what 4 is I can't see the whole problem
$275*x%=195
It will be a 29% reduction. But it will not have the exact cost of $195
For part A, the majority of dots circled are what's called a cluster. The one point out by itself is called an outlier. As for part B, it seems that as the hours of computer games played go down, their test scores go up.
