Answer
$19984.88
Work Step by Step
We can calculate simple interest on a loan by using the formula $I=prt$ (where I is the interest, p is the principal, r is the rate of interest, and t is the amount of time - expressed in years).
$r=5\frac{1}{2}$%$=5.5\div100=.055$
$t=\frac{1}{2}$, because 6 months is equal to .5 years
$I=prt$
$I=19450\times.055\times\frac{1}{2}=534.88$ dollars
Finally, we can find the amount due by adding the interest to the original principal.
$19450+534.88=19984.88$ dollars
