| Determine the yearly rate of interest if $2000 is borrowed for eight months with interest of $120. |
|
Let P = Principle Let R = Rate Let T = Time Let I = Interest Given: P = $2000 Given: I = $120 Given: T = 8 MONTHS Find: R
8
8 months = ---- = (2/3) years
12
Interest = Principle * Rate * TimeI = PRT R = I/PT
120
R = -------------- = 0.09
2000 * (2/3)
R = 9% |
