Question

a television and dvd player cost a total of $1056. the cost of the television is three times the cost of the dvd player. find the cost of each item

Answer 1

The cost of TV is $ 792 and cost of DVD player is $ 264

Solution:

Given, total cost of television and dvd player = 1056

The cost of the television is three times the cost of the dvd player.  

Now, let the cost of DVD player be "n", then the cost TV will be (1056 – n)

And, we know that, cost of TV is 3 times Cost of DVD

$\text { cost of Television } =3 \times \text { cost of DVD }$

$\begin{array}{l}{1056-n=3 \times n} \\\\ {1056=3 n+n} \\\\ {4 n=1056} \\\\ {n=264}\end{array}$

So, the cost of DVD player is $264, the cost of TV will be (1056 - 264) = $792
