Question

A speeding ticket costs $100 plus $20 for each km per hour over the speed limit the violator was traveling. write a numerical expression and find the amount of a ticket for someone going 8 km per hour faster than the speed limit.

Answer 1

The numerical expression for the speeding ticket cost is '$100 + ($20 × number of km/h over speed limit)', and for someone going 8 km/h over the limit, the ticket would cost $260.

Step-by-step explanation:

The numerical expression for the cost of the speeding ticket is $100 + ($20 × number of km/h over speed limit). Since the driver was going 8 km/h over the speed limit, we use the expression:

$100 + ($20 × 8)

Now, we calculate:

$100 + ($20 × 8) = $100 + $160 = $260

Therefore, the amount of the ticket for someone going 8 km/h faster than the speed limit would be $260.
