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)
