You are given the cost per item and the fixed costs. Assuming a linear cost model, find the cost equation, where C is cost and x is the number produced. Cost per item = $7, fixed cost = $9350 C(x) =

Assume it costs Microsoft $4,300 to manufacture 5 Xbox 360s and $6,850 to manufacture 10. Obtain the corresponding linear cost function. C(x) =        What was the cost (in dollars) to manufacture each additional Xbox? $  Use the cost function to estimate the cost of manufacturing 50 Xboxes (in dollars). $

It costs $1000 to produce 100 t-shirts in a day, and it costs $1300 to produce 140 t-shirts in a day. Assume that the daily cost is a linear function of the number of t-shirts produced per day.a. Determine the marginal cost per t-shirt.b. Determine the fixed daily cost.

A family plan  for a cell phone has a monthly price of $75 plus $10.99 for each additional family member added beyond the primary account holder. The linear function to model the monthly cost C(x) in ($) of a family for x additional family members added is C(x)=
