Question

The total cost 2 similar televisions and 5 similar washing machines is 7215 dollar . Each washing machine cost 216 dollar less than a television. How much do 3 televisions cost?

Answer 1

Answer:

3555 dollar

Step-by-step explanation:

Let Television be "T" and Washing machine be "W".

Given that

1. 2T + 5W = 7215
2. 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
