Final answer:
The correct equation to determine the number of months Enrique has paid the book club is 14.99x = 134.91, where x is the number of months.
Therefore, the correct answer is: option C). 14.99x = 134.91
Step-by-step explanation:
The equation to determine the number of months, x, Enrique has paid the book club can be represented by 14.99 times the number of months equals the total amount paid, which is 134.91.
The correct equation, therefore, is 14.99x = 134.91, where x represents the number of months.
This is a linear equation because it can be written in the form of y = mx, where m is the slope and x is the independent variable.
