Question

Bill bought a computer and a printer for a total of $650. The computer cost $525. How much did he pay for the printer alone? (Let p stand for the cost of the printer.)

Answer 1

$125

Explanation:

The computer and the printer cost $650. The computer alone cost $525. P is the cost of the printer that Bill pay.

P=$650-$525

=$125

Answer 2

$125

Explanation:

Let p stand for the cost of printer

Let c stand for the cost of computer

We know that:

c + p = 650

c = 525

So,

525 + p = 650

Subtract 525 from both side, we got:

525 -525 + p = 650 - 525

0 + p = 125

p = 125

So the cost of the printer is $125
