Answer: $454.55
Step-by-step explanation:
Tito's weekly salary is always $ 500 per week.
But your weekly commission income depends on the sales you make. Your commissions are 55%.
If we call x the dollar amount of all sales made by Tito in a week, then his income z(x) is given by the following equation:
[tex]z (x) = 0.55x + 500[/tex]
We wish that [tex]z (x) = 750[/tex].
Then we equate the equation to 750 and solve for the variable x.
[tex]0.55x + 500 = 750\\\\0.55x + 500-500 = 750-500\\\\0.55x = 250[/tex]
[tex]\frac{0.55}{0.55}x = \frac{250}{0.55}[/tex]
[tex]x = \$\ 454.55[/tex]
Total sales made by Tito must be $454.55
