Answer
$\$ 11,375.00$
Work Step by Step
The future value ($FV=?$) of an investment of
$PV=10,000$ dollars
at an annual simple interest rate of
$r =11\displaystyle \%=\frac{11}{100}=0.11$
for a period of
$t =$ ($15$ months)$\displaystyle \cdot\frac{1\ year}{12\ months}=\frac{15}{12}$ years
$=1.25$ years
is
$FV=PV(1+rt)$
$FV=10,000(1+0.11(1.25)=$11375
