Tammy bought 16 cookies for a party. She had 6 6 cookies decorated at an extra cost of 25 cents each. If the total cost of the cookies $9.50, how much did each plan cookie cost?

    Sorry it was a mistake... It was only 6 cookies (typo_not 66)

  • Math - ,

    basic cost of cookie = x
    fancy cookie = x+25

    so 10x + 6(x+25) = 950

    So that's how much each plain cookie cost?

  • Math - ,

    I defined x to be cost of a basic cookie, so whatever you got for x in solving the equation is the cost of the cookie.

    I hope you got 50 cents.
