Hi Fiza.
As you wrote the question, the correct answer is C.
However, you have left out a key detail. 450 is supposed to be 450�.
With that detail added, even considering both statements, one can find many values for c that work.
Therefore, the correct answer is E.

To expand on that, if we have
10 * 6 * 5ᶜ = 450�
we can divide both sides by 30 to find
5ᶜ * 2 = 15 * 450��¹
Since c doesn't have to be an integer, there can be any number of solutions.
10 * 6 * 5ᶜ = 450�
we can divide both sides by 30 to find
5ᶜ * 2 = 15 * 450��¹
Since c doesn't have to be an integer, there can be any number of solutions.
