The Charlotte Motor Speedway determines their pricing as follows: r(x)=200[(x-90)]+k
Note that x represents the number of minutes on the track and that r(x) represents the total price in dollars.
Cole Trickle and Rowdy Burns are drivers that have rented the track.
- Cole's team spent $1000 for the time that he drove.
- Rowdy's team spent $800 for the 70 minutes that he drove.
If Cole and Rowdy had been able to combine their minute's total, they would have only paid a total of $1400.
What is the range of minutes (x) that Cole could have driven at the racetrack?

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

what i would say the best answer is a. 40.5
