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.

Answer: 150 pieces
Step-by-step explanation:
Kiran has used 4/5 of the pieces of the puzzle.
This number translates to 120 pieces.
Assuming the total number of pieces is x, the formula for the total number is:
4/5x = 120
x = 120 ÷ 4/5
x = 120 * 5/4
x = 150 pieces
