Joni’s total interest earned is 0.125% of her investment.
Solution:
Given that
Interest earned by Joni per day = $0.625
Investment done by Joni = $1000
Duration of earning interest = 2 days
Total interest earned = interest earned by Joni
duration of interest earned.
= 0.625
2 = $1.25
So Joni’s total interest earned is 0.125% of her investment.
