Xavier is a salesperson who is paid a fixed amount of $455 per week. He also earns a commission of 3% on the sales he makes. If

Oksi-84 [34.3K]

He needs to make $4,000 in sales in order to hit $575 so if he earns more than $4,000 in sales then he will exceed his goal. I did 575-455=120 to see how much he needs. Then I did 0.03×4=0.12. Well if you add 0's you will get 120 because the decimal will move so then I added 3 0's to get 0.03×4,000=120. Hope this helped.

HELP!

You have to factor the equation you're given. (To check you factorization you can "FOIL" it and make sure it matches the original equation)

Then set the two answers you get from FOILing to zero and you should get your answers.
