Answer:
The correct option is C.
Step-by-step explanation:
The given cubic equation is

According to the rational root theorem 1 and -1 are possible rational roots of all polynomial.
At x=-1, the value of function 0. Therefore (x+1) is the factor of polynomial and -1 is a real root.
Use synthetic division to find the remaining polynomial.


Using 

USe zero product property and equate each factor equal to 0.

Therefore the equation have three real roots out of which the value of two roots are same.
Option C is correct.
To find the price per spoon of brand A, divide the cost by the amount of spoons:
