Question

Linear Transformations

Answer 1

The following equation gives the monthly cost of running a manufacturing facility, C(x), in dollars, as a function of the number of units produced, x, per month.
C(x) = 150x + 5,500

If 500 is added to the y-intercept of the equation to arrive at a new equation for calculating costs, then which of the following is true?

Answer 2

The cost of producing 1,500 units will increase by 500 dollars.

The cost of producing a unit will increase by 500 dollars per unit.

The fixed costs of running the facility will increase by 500 dollars per month.

The number of units produced per month will increase by 500 dollars.
