At one point, some Treasury bonds were callable. Consider the prices on the following three Treasury issues as of May $15,2019$:

$\backslash$table$[[7\mathrm{.}05,$May$23,110\mathrm{.}31250,110\mathrm{.}37500,-\mathrm{.}37500,5\mathrm{.}39],[8\mathrm{.}80,$May$23,107\mathrm{.}43750,107\mathrm{.}50000,-\mathrm{.}12500,5\mathrm{.}35],[12\mathrm{.}55,$May$23,145\mathrm{.}93750,146\mathrm{.}12500,-\mathrm{.}43750,5\mathrm{.}43]]$

The bond in the middle is callable in February $2020.$ What is the implied value of the call feature? Assume a par value of $$1,000.($Hint: Is there a way to combine the two noncallable issues to create an issue that has the same coupon as the callable bond?$)($Do not round intermediate calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
