a computer and printer cost a total of $1038. the cost of the computer is two times the cost of the printer. find the cost of each item

Sagot :

You can do cost of printer = x, so cost of computer is 2x. That means that 1038 = 3x. So you divide by three on both sides and get x = 346, which means the printer is $346 and the computer is twice that, or $692.
