So,
Remember that the simple interest of an initial amount after "t" years, can be found using the following formula:
Where A is the final amount, P is the initial amount, r is the rate and t are the years involved.
If we replace our values, Emma will has the following amount after 8 years:
So, Emma will has $2,960 after 8 years.
To find the amount that Paul will has, we should remember what the compound interest is.
Remember that the compound interest is given by the formula:
Where A is the final amount, P is the initial amount, i is the rate and n are the years involved.
If we replace our values, Paul will has the following amount of money after 8 years:
So, Paul will has $3187,70 after 8 years.
Therefore, the correct answer is A.
