Hagrid has a chance to expand the Hogwarts property by purchasing $210-$acres of the forbidden forest from the centaurs. According to Dr$.$ Sprout, there has been an increase in the demand for Mandrake restorative draught, so Hagrid has agreed to farm Mandrakes on the acres he purchases. The expected mandrake yield is $185$ units per acre. The centaurs will sell the land for $$7,200/$acre$.$ Hagrid can borrow the money from Gringotts Wizarding Bank to finance the land at a $4\mathrm{.}7\%$ annual interest rate. Hagrid expects inflation to be $1\mathrm{.}9\%($the economy is looking up after the departure of he$-$who$-$must$-$not$-$be$-$named$).$

Please round to FOUR decimal places throughout, with the exception of dollars$/$cents and percentages, which may be rounded to only $2$ decimal places.

A$.$ Estimate the average annual ownership cost per acre $($do not multiply and divide by the number of acres in the tract$)$ for that expansion. $($Hint: For an input with unlimited life there is no depreciation and the interest is just the value times the real interest rate.$)$ Land maintenance, including tile repair, will be about $$3\mathrm{.}75$ per acre annually, taxes are $$29$ per acre, and liability insurance is $$0\mathrm{.}95$ per acre $($Fairly low considering the deadly Mandrake cry$)$
