Daniel is enrolling for a test prep class. the expression below represents the hourly charges, including the cost for the materials. $30x + $65 1. the constant of the expression represents the a. cost of materials b. cost per hour c. number of hours 2. and the coefficient of x represents the__ a. cost per hour b. cost of materials c. number of hours

Step-by-step explanation:

The given expression is

This is a linear expression in slope-intercept form, where the constant ratio of change is 30, and the y-intercept is at y = 65.

Now, according to the problem, the expression represents the hourly charges, including the cost for the materials.

Therefore, the hourly charge is $30 per hour, where x represents hours, and the cost for materials is $65.

So, the answer to the first question is: A. cost of materials.
