Acomputer and printer cost a total of 1136 . the cost of the computer is three times the cost of the printer. find the cost of each item.

Let's assign each a variable: 

Computer: 3x
Printer: x

We know that the total is 1136, so:

x+3x=1136
4x=1136

Now, we divide 1136 by 4 to get the cost of the printer.

1136/4=284

So, now let's apply this to what we wrote previously.

Printer: 284
Computer: 284*3= 852
