If a customer uses 340 minutes, the monthly cost will be $175. If the customer uses 770 minutes, the monthly cost will be 5347. A) Find an equation in the form y = max + b, where a is the number of monthly minutes used and y is the total monthly cost of the Ringular plan. Answer. y = B) Use your equation to find the total monthly cost if 841 minutes are used. Answer: If 841 minutes are used, the total cost will be dollars.

The accounting department has determined that the cost function for this new product will be C(x) = 1701 + 6850 and the revenue function will be R(z) - 220z, where a is the number of units sold. Additionally, the sales department has determined that you reasonably can expect to sell around 149 units. You must decide whether to go ahead with the new product line. Find the break-even quantity. Find the profit function: P(x) = Make your decision: Cancel the product line: the quantity needed to break even is more than our firm can reasonably expect to sell. Cancel the product line: producing these products is not profitable. Proceed with the product line: the products are profitable and we can reasonably expect to meet our break-even quantity.
