Race-car drivers earn $20 per lap they complete around the track. Race-car drivers usually complete 10 laps around the track during an event. Race-car drivers earn 3 times the total amount they earn during an event for every extra lap they complete on the race track.
If a race-car driver completes 15 laps during the event, how much did the race car driver earn for that event?

Answer 1

3200

Step-by-step explanation:

First you need to find out how much the driver makes for the normal 10 lap event. $20 per lap for 10 laps is $200.

Now the driver earns 3x that amount for every lap over the normal 10 laps. So for every extra lap, the driver earns $600. Five extra laps would give him $3000.

So for the total 15 laps the drive would earn the initial $200 plus the extra $3000 or $3200 total.

Answer 2

Answer: 900

Step-by-step explanation:

If they earn 3 times the amount during an event, that's 60, multiply that by the number of laps.

20 x 3 = 60

60 x 15 = 900
