The cost $C(x)$, in dollars, of operating a bakery for one day to produce $x$ loaves of bread is given by the function $C(x)=mx+75$, where $m$ is the variable cost per loaf and $75$ is the fixed daily cost. If the total cost to produce 30 loaves is $195, what is the total cost, in dollars, to produce 200 loaves on a given day? (Disregard the $ sign when gridding your answer.)
