Question 1146328
<br>
The 5.5% (= 0.055) is the annual interest rate.  For daily compound interest, a year is often considered 360 days; so the daily interest rate is 0.055/360.<br>
March 20 to April 20 is 31 days, so the amount on April 20 will be<br>
{{{1000(1+0.055/360)^31}}}<br>
Use a calculator....<br>
(You can of course use 0.055/365 -- or even 0.055/365.25 -- in that calculation if you want.)
