Renting Paddleboats An enterprise rents out paddleboats for all-day use on a lake. The owner knows that he can rent out all 27 of his paddleboats if he chargers $1 for each rental. He also knows that he can rent out only 26 if he chargers $2 for each rental and that, in general, there will be 1 less paddleboat rental for each extra dollar that he charges per rental.
a. What would the owner’s total revenue be if he charged $3 for each paddleboat rental?
b. Use a formula to express the number of rentals as a function of the amount charged for each rental.
c. Use a formula to express the total revenues as a function of the amount charged for each rental.
d. How much should the owner charge to get the largest total revenue?

- Sales Commissions A saleswoman works at a kiosk that offers three different models of cell phones: standard with 16 GB capacity, deluxe with 32 GB capacity, and super deluxe with 64 GB capacity. For each phone that she sells, she earns a commission based on the cell phone model. One week she sells 9 standard, 11 deluxe, and 8 super-deluxe and makes $740 in commission. The next week she sells 13 standard, 15 deluxe, and 16 super-deluxe for a $1204 commission. The third week she sells 8 standard, 7 deluxe, and 14 super-deluxe, earning $828 in commission. (a) Let x, y, and z represent the commission she earns on standard, deluxe, and super-deluxe, respectively. Translate the given information into a system of equations in x, y, and z. (b) Express the system of equations you found in part (a) as a matrix equation of the form AX=B . (c) Find the inverse of the coefficient matrix A and use it to solve the matrix equation in part (b). How much commission does the saleswoman earn on each model of cell phone?arrow_forwardAmerican Dollars and British Pounds Assume that at the current exchange rate, the British pound is worth 1.65 in American dollars. You have some dollars bills and several British pound coins. There are 17 items altogether, which have a total value of 20.25 in American dollars. How many American dollars and how many British pound coins do you have?arrow_forwardWholesale distribution Ace Electronics, Hi-Fi Stereo, and CD World buy a total of 175 DVD players from the same distributor each month. Because CD World buys 25 more units than the other two stores combined, CD Worlds cost is only 160 per unit. The players cost Hi-Fi 165 each and Ace 170 each. How many players does each retailer buy each month if the distributor receives 28,500 each month from the sale of the players to the three stores?arrow_forward
- APPLICATIONS Classroom UseA small school has 100 students who occupy three classrooms: A, B. and C. After the first period of the school day, half the students in room A move to room B, one- fifth of the students in room B move to room C, and one-third of the students in room C move to room A. Nevertheless, the total number of students in each room is the same for both periods. How many students occupy each room?arrow_forwardShipping TelevisionsAn electronics discount chain has a sale on certain brand of 60-in. high-definition television set. The chain has stores in Santa Monica and El Toro and warehouses in Long Beach and Pasadena. To satisfy rush orders, 15 sets must be shipped from the warehouses to the Santa Monica store, and 19 must be shipped to the El Toro store. The cost of shipping a set is 5 from Long Beach to Santa Monica, 6 from Long Beach to El Toro, 4 from Pasadena to Santa Monica, and 5.50 from Pasadena to El Toro. If the Long Beach warehouse has 24 sets and the Pasadena warehouse has 18 sets in stock, how many sets should be shipped from each warehouse to each store to fill the orders at a minimum shipping cost?arrow_forwardAgriculture A mixture of 6 gallons of chemical A, 8 gallons of chemical B, and 13 gallons of chemical C is required to kill a destructive crop insect.
