A costumer at a raceway can drive 54 laps around the track for 12$. At this rate, how many laps can the customer rive for 8$?
raketka [301]

Answer:

36 laps can the customer rive for $8 .

Step-by-step explanation:

As given

A costumer at a raceway can drive 54 laps around the track for $12.

I.e

54 laps cost = $12

Now calculate laps for $1.

\$1 = \frac{54}{12}\ laps

\$1 = 4.5\ laps

The number of laps customer rive $8 = 4.5 × 8

                                                              = 36 laps

Therefore 36 laps can the customer rive for $8 .
