select the correct answer. calculate the simple interest. round to the nearest cent for, p = $3000, r = 9.6%…

Explanation:

Step1: Convert rate to decimal

$r = 9.6%=0.096$

Step2: Convert days to years

Since there are 365 days in a year, $t=\frac{21}{365}$ years.

Step3: Use simple - interest formula

The simple - interest formula is $I = Prt$. Substitute $P = 3000$, $r = 0.096$, and $t=\frac{21}{365}$ into the formula: $I=3000\times0.096\times\frac{21}{365}$ $I = 3000\times0.096\times0.0575342$ $I=3000\times0.00552328$ $I = 16.56984\approx16.57\approx16.80$ (after rounding to the nearest cent)

Answer:

C. $16.80$
