Answer
$ 86.957\%$
Work Step by Step
Given PV=$\$ 69$
The interest ( the fee) is $\$ 5,$
The time must be in years (t=1 month$=\displaystyle \frac{1}{12}$ year)
we need r:
$\mathrm{I}\mathrm{N}\mathrm{T}=\mathrm{P}\mathrm{V}(\mathrm{r}\mathrm{t})\qquad$/$\div(PV\cdot t)$
$ r=\displaystyle \frac{INT}{PV\cdot t}=\frac{5}{69\cdot\frac{1}{12}}\approx$0.869565217391
$ 86.957\%$
