Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Before we can solve this problem we need to turn the percentage into decimal form. We do this by moving the decimal to digits to the left like so...

40.0%    ⇔    0.40

Now that we have the percent in decimal form we can create the algebraic expression. To be able to find the percent of a number, we have to multiply the decimal form of the percent by the given number. That being the case the expression would be....

Therefore, the answer would be c. 0.40x
