The Missing Link Chain$-$Link Fence Company is trying to determine how many chain$-$link fabricating machines to buy for its factory. If we define a chain$-$link fence of some specified length to be equal to one unit of output, the price of a new fabricating machine is $60$ units of output, and the price of a one$-$year$-$old machine is $48$ units of output. These relative prices are expected to be the same in the future. The expected future marginal product of fabricating machines, measured in units of output, is:

$MP{K}^f=165-0\mathrm{.}2K,$

where $K$ is the number of machines in use. There are no taxes of any sort. The real interest rate is $11\%$ per year.

a$.$ What is the user cost of capital?

$($Enter your response rounded to one decimal place$).$
