The cost of producing widgets per month at the Acme Widget Factory can be modeled by the relation C = 25 000 + 35w, where C represents total production costs in dollars and w represents the number of widgets produced. The y-intercept of this relation represents: |
| | A) | …the cost to produce each widget. |
| | B) | …how much the factory spends on things like rent and taxes which don’t depend on how many widgets are produced. |
| | C) | …revenue earned from producing widgets. |
| | D) | …how many widgets the factory produces each month. |
