4 Vehicle in 1 Minute
4 Vehicle*60 in 60 Minute(1 Hour) = 240 Vehicle in 1 Hour
Total time duration (6 o'clock yesterday morning to 12 o'clock midnight) = 18 hrs
Total tollbooths = 7
Cost of each vehicle passed = $0.75 Therefore, Total cost collected = 240 * 18 * 7 * 0.75 = 22680 = 23000 (approx) Hence, D. _________________ The few, the fearless !

Hence D (I've rounded up a few numbers above for easy calculation)

OA:D
Total hours: $$18 hours$$
Total Vehicles passed per toll booth per hour : $$4*60 =240$$
Toll collected per vehicle :$$0.75$$
Number of Toll booths:$$7$$
Total money collected = Total hours * Total Vehicles passed per toll booth per hour *Toll collected per vehicle *Number of Tollbooths
= $$18*240*0.75*7=22680$$

We can create the expression:

7 tollbooths x $0.75 per vehicle x 4 vehicles per minute x 60 minutes x 18 hours =$22,680 ≈ $23,000 Answer: D _________________ Scott Woodbury-Stewart Founder and CEO GMAT Quant Self-Study Course 500+ lessons 3000+ practice problems 800+ HD solutions Director Joined: 19 Oct 2013 Posts: 509 Location: Kuwait GPA: 3.2 WE: Engineering (Real Estate) Re: A certain toll station on a highway has 7 tollbooths, and each tollboo [#permalink] ### Show Tags 19 Oct 2018, 04:23 1 Bunuel wrote: A certain toll station on a highway has 7 tollbooths, and each tollbooth collects$0.75 from each vehicle that passes it.

NEW question from GMAT® Quantitative Review 2019

(PS01443)

6AM to 6PM = 12 hours then another 6 hours to midnight total 18 hours.

18 * 60 = 1,080 minutes * 4 cars = 4,320 cars passing.

Since the cost each car is 0.75 which equals 3/4

so 3/4 * 4,320 = 3 * 1,080 * 7(for the tollbooths) = 21 * 1,080

No need to go through tedious calculations 20 * 1,000 = 20,000 there is only one answer with such thousands digit.
