Answer:
TV 1,955
REMOTE 115
INSTALLATION 230
Explanation:
We are going to calculate the total sum of the element of the offer and then cross-multiply
[tex]\left[\begin{array}{ccc}$TV&2040&a\\$Remote&120&b\\$Installation&240&c\\$Total&2400&2300\\\end{array}\right][/tex]
[tex]a = \frac{2040}{2400 } * 2300 = 1,955[/tex]
[tex]b = \frac{120}{2400 } * 2300 = 115[/tex]
[tex]c = \frac{240}{2400 } * 2300 = 230[/tex]
