Start by writing the total as an equality
[tex]A+B=350[/tex]Then find 2 expressions for A and B
A will be your reference point
[tex]A=A[/tex]If B is 24 millions less than A then
[tex]B=A-24[/tex]put this 2 expressions into the first equation and solve for A
[tex]\begin{gathered} A+(A-24)=350 \\ 2A-24=350 \\ 2A=374 \\ A=374 \\ A=187 \end{gathered}[/tex]According to this singer A made 187 millions and singer B made 163 millions.
[tex]\begin{gathered} B=A-24 \\ B=187-24 \\ B=163 \end{gathered}[/tex]
