Hi there!
First, let's set up an expression for each printer:
A: x
B: x + 12
Then, we know that when both printers are printing the report, it only takes 8 minutes. So, when averaged, that is how long it would take for the report to be printed. Here is our equation and solving:
1/2(2x + 12) = 8
x + 6 = 8
x = 2
Now, we know that x equals 2. This means that Printer A takes 2 minutes to print a report and Printer B takes 14 minutes to print a report.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
