In a recent? year, person A and person B had two concert? tours, and together they generated $ 192.9 million in ticket sales. If

Nuetrik [128]

Answer: Person A generates 107.6 millions and person B generates 85.3 millions.

Step-by-step explanation:

Let 'x' millions be the amount generated by person A then the amount generated by person B be 'x-22.3' millions.

Since they both earn together $192.9 millions.

So according to the our assumptions we have,

$x+x-22.3=192.9\\\Rightarrow\ 2x=192.9+22.3\\\Rightarrow\ 2x=215.2\\\Rightarrow\ x=107.6$

Therefore, the amount generated by person A=107.6 millions

And the amount generated by person B= 192.9 millions - 107.6 millions

=85.3 millions
