The RideEm Bicycles factory can produce 140 bicycles in a day at a total cost of \$10,200 and it can produce 160 bicycles in a day at a total cost of \$10,900.

What are the company's daily fixed costs?

What is the marginal cost per bicycle?(How do I find this function?)

Thank you.

20 extra bikes cost \$700 more to produce. That is \$35 per bike. That is the marginal cost.

When producing 140 bikes, the per-bike part of the cost is 140x35 = \$4900

The "daily fixed cost" (labor/rent/overhead) is 10,200 -4900 = \$5300.
