Question 864616
Let's assume there are 365 days in the year (sometimes banks use 360 days in the year, but we'll go with 365 since it's more accurate). This would mean 270 days turns into 270/365 years. Because t is usually in years, t = 270/365



The deposit is $4,000, so P = 4000



The interest rate is 9.5% ---> 9.5/100 = 0.095 so r = 0.095



We'll use these to plug them into the formula I = P*r*t



----------------------------------------------------------------------



I = P*r*t



I = 4000*0.095*(270/365)



I = 281.095890410959 <font color="blue">use a calculator here</font>



I = 281.10 <font color="blue">round to the nearest penny</font>



So you've earned <font size=4 color="red">$281.10</font> in interest.
