The paycheck of the first salesperson's is 791.67$ while the paycheck of the second salesperson's is 633.33$
Let:
x: First salesperson's weekday
y: Second salesperson's weekday
So, we know that a salesperson's weekday paycheck is 25% more than a second salesperson's paycheck, this can be written as:
[tex]x=y+(25 \%)y \\ \\ x=y+0.25y \\ \\ x=1.25y[/tex]
We also know that the two paychecks total $1425, so this can be written as:
[tex]x+y=1425[/tex]
By using substitution method:
[tex](1) \ x=1.25y \\ \\ (2) \ x+y=1425 \\ \\ Substituting \ 1 \ into \ 2: \\ \\ 1.25y+y=1425 \\ \\ Combining \ like \ terms: \\ \\ 2.25y=1425 \\ \\ Isolating \ y: \\ \\ y=\frac{1425}{2.25}=633.33 \\ \\ Finding \ x, from \ 2: \\ \\ x=1425-633.33=791.67[/tex]
Finally:
The paycheck of the first salesperson's is 791.67$ while the paycheck of the second salesperson's is 633.33$
