Answer with explanation:

Cost, in dollars,(C)→  C = 4 8 x + 18, where x is the number of hours worked.

This is Linear equation in two variable, where C is the total amount Charged for number of Hours(x), worked.

If you will look at the Equation of line in slope intercept form in two variables,

y = m x + c, where, m=48, c=18

⇒4 8 x = Hourly Rate, for, x=1,2,3,

⇒18 = Overhead Charge

You can inspect this by , putting , x=1 , 2 ,3, in the equation of Cost Equation.

For, Example, C(1)=48 ×1 +18

C(2)=48 × 2 + 18

C(3)= 48×3+18

So, every time , number 18 is added to the term 48 x, for different values of x.

Option A:→ 48 signifies the hourly rate, and 18 signifies the overhead charge.
