Quadratic equation problem

[jsaunders94]

How would I set up a equation for this quadratic word problem , John operates a small sign-making business . He finds that if he charges x dollars for each sign, he sells 49-x signs per week. What is the smallest number of signs that he can sell to have an income of $510 in one week?

Hi Saunders:

I don't understand. Tutors have asked you three times to follow the forum guidelines.

Did you read the guidelines, yet?

Hint: [weekly income] = (dollars charged per sign) times (number of signs sold per week)

Cheers :cool:
