Kenisha sells athletic shoes parttime at a department store. She can earn either $500 per month plus a 4% commission on her total sales, or $400 per month plus a 5% commission on total sales.
Write a system of equations to represent the situation.
What is the total price of the athletic shoes Kenisha needs to sell to earn the same income from each pay scale?
Which is the better offer?

I answered this question previously. However, here it is again.
$500 + .04x = $400 + .05x
x will give you the amount she has to sell to get the same income.
The better offer depends on how good a salesperson she is, how much she expects to sell.
I hope this helps again. Thanks for asking.
