Lisa [10]

9514 1404 393

Answer:

  The equation should be 8 (x minus 2.75) = 78, and she needs to sell each necklace for $12.50.

Step-by-step explanation:

The contribution margin of each necklace is the difference between its selling price (x) and its cost (2.75). Then the total profit from 8 necklaces would be ...

  8(x -2.75)

If Rita wants that profit to be $78, then she needs to solve the equation ...

  8(x -2.75) = 78 . . . . correct equation

The solution is ...

  x -2.75 = 9.75 . . . . divide by 8

  x = 12.50 . . . . . . . . add 2.75

She needs to sell each necklace for $12.50.
