What is the amount of interest earned with a deposit of 7,000 at 6.5% for 120 days

I = Prt Always remember this. It si the essence fo Simple Interest.
We have P = 5000
I = (5000)rt
We ahve r = 0.085
I = (5000)(0.085)t
We have t = 120 days. This is a little bit of a problem. Different things use different numbers of days for a total year. Let;s just use 365 days for a full year.
I = (5000)(0.085)(120/365)
The interest figure always means the interest for a year.
120 days is 1/3 of a year, so you'll only earn 1/3 of 6.5% .
6.5% = 0.065
1/3 of that is 0.02167 .
(0.02167) x (7,000) = 151.67
