In a recent year, person A and person B had two concert tours, and together they generated $ 192.4 million$192.4 million in ticket sales. If person B took in $21.821.8 million less than person A, how many millions of dollars did each tour generate?

Person A generated $ 107.1 million

Person B generated $ 85.3 million

Explanation:

Let the income generated by the person A = x

and the income generated by the person B = y

Now,

according to the conditions given in the problem

x + y = $ 192.4 million ... (1)

also,

y = x - $ 21.8 million ... (2)

substituting the y from 2 in the equation 1, we get

x + (x - $ 21.8 million) = $ 192.4 million

or

2x - $ 21.8 million = $ 192.4 million

or

2x = $ 214.2 million

or

x = $ 107.1 million

substituting the x in equation 2, we get

y = $ 107.1 million - $ 21.8 million

or

y = $ 85.3 million

hence,

the person A generated $ 107.1 million and the person B generated $ 85.3 million
