Q.

T=1200-0.06 c

\newline

A print shop copies and prints documents in large volume for its customers. For a particular copy machine, the equation gives the amount of toner,

T

, in grams, left after making

c

copies. How many grams of toner are used per copy?

Understand the equation: Understand the equation. $\newline$ The equation $T = 1200 - 0.06c$ represents the amount of toner left ( $T$ ) after making $c$ copies. The initial amount of toner is $1200$ grams, and with each copy made, some amount of toner is used.
Determine toner usage per copy: Determine the amount of toner used per copy. The coefficient of $c$ in the equation represents the amount of toner used per copy. Since the equation is $T = 1200 - 0.06c$ , the amount of toner used per copy is $0.06$ grams.
