Select the correct answer from each drop-down menu.

A vendor sells pretzels on a city street corner. He models the monthly costs, in dollars, to operate his business with function [tex]$C$[/tex], where [tex]$x$[/tex] is the number of pretzels he sells: [tex]$C(x) = 0.63x + 800$[/tex].

Because the vendor sells the pretzels for [tex]$\$[/tex]2.75[tex]$ each, he models his monthly revenue from selling $[/tex]x[tex]$ pretzels with function $[/tex]R[tex]$: $[/tex]R(x) = 2.75x[tex]$.

The function $[/tex]\square[tex]$ represents the vendor's monthly profit, in dollars, when selling $[/tex]x[tex]$ pretzels.

In a month where he sells 600 pretzels, the vendor will make a profit of $[/tex]\[tex]$[/tex] [tex]$\square$[/tex].
