The ratio of the rates of printing of two printers A and B is 6:5. Printer A prints at a rate of (3x + 12) pages per minute. Write an expression to represent the rate of printing of Printer B in terms of x. Both printers started printing at the same time to complete a print job in one hour. What is the total number of printed pages from both printers in terms of x?

How many more printed pages did printer A produce than Printer B.
