1. Write the cost function for this company. C(x) =2052
work1399+(1.87*349)
2. Write the revenue function for this company. R(x) =2056
work 5.89*349
3. What is the minumum number of thingamabobs that the company must produce and sell to make a profit? = 349

1. 1399 + 1.87x
2. 5.89x
3. 589x  (1399 + 1.87x) > 0
