Question

This equation shows how the cost of a cab ride depends on the distance in miles.

c = 3d

The variable d represents the number of miles driven, and the variable c represents the cost in dollars. If a cab ride is 31 miles long, how much will it cost?

$_

Answer 1

To find the cost of a cab ride that is 31 miles long, you can substitute \( d = 31 \) into the equation \( c = 3d \).

So the calculation will be:

\[
c = 3 \times 31
\]

Calculating that gives:

\[
c = 93
\]

Thus, the cost of a 31-mile cab ride will be **$93**.
