A company is producing tires for cars. The weekly cost of producing x tires is given by:

C(x) = 60,000 +500x - 0.75x^2

Find and interpret the marginal cost at a production level of 300 tires a week.

At a production level of 300 tires a week the production costs are increasing at a rate of $50 per tires.

It costs $142,500 to produce 300 tires a week.

At a production level of 300 tires a week the production costs are increasing at a rate of $50 per week

none of these answers.

It costs $145,500 to produce 300 tires a week.
