This is clear, if you don't know how to do it just say that, the lines indicate the next question

"Suppose you owe $17,000 on a credit card that carries an APR of 24%. Because the balance is so high, you choose to stop charging and ff the card. You can afford to make only the minimum mo e minimum monthly payment, which is sox of the bala months is given by e. Then your balance after t B = 17,000(1.02 x 0.95)' dollars. How many payments will you have to make to get the balance below $500? (Enter the smallest such number of payments as an integer.) payments Brzycki's formula is used by weight lifters to determine the weight M that is equivalent in a single repetition to n repetitions of a weight w. The formula is w 1.0278 - 0.0278n It applies for up to n = 10 repetitions. In this exercise we consider a weight lifter who bench-presses several repetitions of w = 265 pounds. (a) What single bench press weight M corresponds to 9 repetitions of this weight? (Round your answer to two decimal places.) M =[ (b) What number of repetitions n of this weight corresponds to a single bench press of 353.43 pounds? (Round your answer to the nearest whole number.) repetitions One model for the number of students enrolled in U.S. public high schools as a function of time since 1986 is the formula below. Here / is the enrollment in millions of students, t is the time in years since 1986, and the model is relevant from 1986 to 1996. (a) Use functional notation to express the number of students enrolled in U.S. public high schools in the year 1987. v Calculate that value. (Round your answer to one decimal place.) million students (b) Explain in practical terms what N(9) means. This answer has not been graded yet. Calculate N(9). (Round your answer to one decimal place.) million students (c) In what year was the enrollment the smallest? The profit P, in thousand of dollars, that a manufacturer makes is a function of the number N of items produced in a year, and the formula is as follows . P = -0.2N2 + 3.6N - 9 (a) Express using functional notation the profit at a production level of 3 items per year. PL Calculate that value. thousand dollars (b) Determine the two break-even points for this manufacturer-that is, the two production levels at which the profit is zero. V = (smaller value) (larger value) (c) Determine the maximum profit if the manufacturer can produce at most 21 in a year. thousand dollars You own a motel with 41 rooms and have a pricing structure that encourages rentals of rooms in groups. One room rents for $81, two rent for $79 each, and in general the group rate per room is found by taking $2 off the base of $81 for each extra room rented. (a) How much money do you take in if a family rents two rooms? (Round your answer to the nearest dollar.) (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 revenue from renting n rooms to a convention host. R(n) = (d) What is the most money you can make from rental to a single group? (Round your answer to the nearest dollar.) How many rooms do you rent? rooms
