Respuesta :

Interest, r, is 9.5%,

Number of days, n, is 91 days,

Let P represent the principal

t is number of times

Where i = (r/365) for daily compounded interest,

[tex]Daily\text{ compounded interest = }P(1+i)^n-P[/tex][tex]\begin{gathered} \text{Daily compounded interest = P(1+}\frac{9.5}{365})^{91}-P \\ =P(1+0.02603)^{91}-P \\ =P(1.02603)-P \\ =1.02603P-P \\ =0.02603 \end{gathered}[/tex]

Hence, the best option is B.
