Question

The red bus Company Charges 150+72 per hour to rent a bus The blue bus company charges 240+54 per hour for what number of hours with the companies charge for the same

Answer 1

It will take them 5 Hours to charge the same. The rental charge will be 510.

I did a manual computation per company: My computation is entirely based on trial and error.

Red Bus Co. has a fixed rental rate of 150 and additional rental of 72 per hour while Blue Bus Co. has a fixed rental rate of 240 and additional rental of 54 per hour. Both fixed rental rate are one time charges only and total rental will vary on the number of hours spent in using both vehicles.

Let's start with the Red Bus Co. I will be posting the charges per hour and its running balance. The running balance is the sum.

Fixed Rate      150    Running Balance: 150    => 150 + 0
Hr 1                    72                                      222   => 150 + 72
Hr 2                    72                                      294  =>  222 + 72
Hr 3                    72                                      366  => 294  + 72
Hr 4                    72                                      438  => 366 + 72
Hr 5                    72                                      510  => 438 + 72

I'll do the same process with Blue Bus Co.

Fixed Rate  240      Running Balanc:  240 => 240 + 0
Hr 1                54                                      294 => 240 + 54
Hr 2                54                                       348 => 294 + 54
Hr 3                54                                      402 => 348 + 54
Hr 4                54                                      456 => 402 + 54
Hr 5                54                                      510 => 456 + 54
