The heat that can be dissipated by the human body, per time, is a function of a number of different things. I've been studying a particular person, and I've found the below equation to calculate the Heat Flow Q $($in Watts$)$ as a function of their Skin Temperature T $($in degrees Celsius$).$

Q $\{$W$\}=1\mathrm{.}2*($ T $\{$C$\}-27\mathrm{.}8)$

However, I don't want to work in SI units. I want you alter this equation to accept Skin Temperature T in degrees Fahrenheit and calculate Heat Flow Q in BTU per hour.

Convert the equation and collect terms. The form of your new equation must be as seen below:

Q $\{$BTU$/$hr$\}=$ X $*$ T $\{$F$\}-$ Y $\{$BTU$/$hr$\}$

Report the new value for the constant Y$,$ without units, in the blank below, rounded to one $(1)$ decimal place.
