Question

A printer and monitor together cost $356$. The monitor costs $20$ more than two times the printer. How much do the printer and monitor cost separately?

• A. $244$
• B. $243$
• C. $245$
• D. $250$

Answer 1

The correct option is A $244$

Let the cost of printer be $P$ and the cost of monitor be $M$
We have $P+M=356$ , $M=20+2P$
By solving, we get $3P+20=356$, which implies $P=112$
Therefore $M=356-112=244$
