Question

The RideEm bicycles factory can produce 100 bicycles in a day at a total cost of $10,100, and it can produce 120 bicycles in a day at a total cost of $10,700.
A)Find a linear function that models the total cost for RideEm to produce x bicycles
B) what are the companies daily fixed costs and variable costs?

Answer 1

c = a n + b
10100 = 100 a + b
10700 = 120 a + b
=====================subtract
-600 = -20 a
a = 30 etc. go back and get b
-600 = -20 a
