A rental car agency charges $29.00 per day and 25 cents per mile. (a) Calculate the rental charge if you rent a car for 5 days and drive 300 miles. (Round your answer to the nearest cent.)$ (b) Use a formula to express the cost of renting a car as a function of the number of days you keep it and the number of miles you drive. (Let d be the number of days you rent the car, m the number of miles you drive the car, and C the cost in dollars of renting the car.)C(d, m) = 29d+0.25m (c) It is about 250 miles from Dallas to Austin. Use functional notation to express the cost to rent a car in Dallas, drive it to Austin, and return it in Dallas 1 week later. Use the formula from part (b) to calculate the cost.

Question D, The graph
The yearly profit P for a widget producer is a function of the number n of widgets sold. The formula is given below. P = −180 + 100n − 4n2 Here P is measured in thousands of dollars, n is measured in thousands of widgets, and the formula is valid up to a level of 20 thousand widgets sold. (a) Make the graph of P versus n. (b) Calculate P(0).P(0) = -180 Explain in practical terms what your answer means. The producer will still make a profit if no widgets are soldThe producer will have a loss if no widgets are sold (c) What profit will the producer make if 12 thousand widgets are sold? thousand dollars(d) The break-even point is the sales level at which the profit is 0. Approximate the break-even point for this widget producer. thousand widgets(e) What is the largest profit possible? thousand dollars

You own a motel with 30 rooms and have a pricing structure that encourages rentals of rooms in groups. One room rents for $75.00, two for $73.00 each, and in general the group rate per room is found by taking $2 off the base of $75 for each extra room rented. (b) Use a formula to give the rate you charge for each room if you rent n rooms to an organization. (c) Find a formula for a function R = R(n) that gives the total revenue from renting n rooms to a convention host. (d) Use functional notation to show the total revenue from renting a block of 7 rooms to a group. Calculate the value.
