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:
-0.1 and 0.1
Step-by-step explanation:
A fourth root is a number which multiplied by itself 4 times gives 0.0001.
Since it is an even root and the result is positive, the answer must include both negative and positive values. This is true since a negative times a negative is a positive.
0.1*0.1*0.1*0.1 = 0.0001
So the real fourth roots are -0.1 and 0.1.
