Answer: 
Step-by-step explanation:
Let x be the price. 20% (0.20) 7.25% (0.0725)

We must graph y=x^3-9x^2+11x+21. Please, see the attached file.
Then we see were the graph cuts the x-axis, and these values of x are the real solutions of the given equation:
The real solutions of the given equation are:x = -1, 3, and 7
Variables next to each other can be regarded as being multiplied by each other, so another way to rewrite this could be A * A * A * A * B * B. From there, you can reach
Step-by-step explanation:
5x - 7 = 13
5x = 13 + 7
5x = 20
x = 20 ÷ 4 = 5
10x - 14
10(5) - 14 = 50 - 14 = 36
