Question 1004728: Cal's Carriage Rides charges $20 plus $4.50 an hour for rides in the park. Hal's Horse and Buggy charges $30 plus $2.50 an hour for the same service. For how many hours would you pay the same total fee for a ride? What is that fee?

You can put this solution on YOUR website!
Let x be the number of hours...we set the two fees equal to find the number of hours that makes them so...so we have
20 + 4.5x = 30 + 2.5x
2x = 10
x = 5 hours
Plugging into either charge, we get
20 + (4.5)(5) = $42.50
