Ms.sue so which one is the answer I don't get it
The formula for this is I = PRT
I = Interest
P = Principal (starting amount) = $7,000
R = Rate (percentage) = 8% = .08
T = Time in years = days/years = 122/365

I = 7000(.08)(122/365)
I = $187.178
I = $187.18 (rounded)

B. $187.18

Ps: When the time is less than a year you have to convert it like I did above.
