Answer:
3555 dollar
Step-by-step explanation:
Let Television be "T" and Washing machine be "W".
Given that
- 2T + 5W = 7215
- W = T - 216
Therefore replacing the value of W in eq. 1
We get
2T + 5 ( T-216 ) = 7215
=> 2T + 5T - 1080 = 7215
=> 7T = 8295
=> T = 8295 / 7
Therefore cost of 3 television set = ( 8295 / 7 ) x 3
= 3555
