To find the cost of cleaning 1 room using the equation \( c = 61r \), we substitute \( r = 1 \) into the equation:
\[
c = 61 \times 1
\]
Calculating this gives:
\[
c = 61
\]
So, if the carpet cleaner cleaned 1 room, it would cost **$61**.
\[
c = 61 \times 1
\]
Calculating this gives:
\[
c = 61
\]
So, if the carpet cleaner cleaned 1 room, it would cost **$61**.
