- Getting a Formula In Exercises S-4 through S-13, a verbal description of a function is given. Use a formula to express the function. You pay 500 to rent a special area in a restaurant. In addition, you pay 10 for each guest. Write a formula that gives your total cost C, in dollars, as a function of the number n of dinner guests.arrow_forwardGetting a Formula In Exercises S-4 through S-13, a verbal description of a function is given. Use a formula to express the function. You sell lemonade for 25 cents per glass. You invested 2.00 in the ingredients. Write a formula that gives the profit P=P(n) as a function of the number n of glasses you sell.arrow_forwardGetting a Formula In Exercises S-4 through S-13, a verbal description of a function is given.

- Getting a Formula In Exercises S-4 through S-13, a verbal description of a function is given. Use a formula to express the function. You currently have 500 in a piggy bank. You add 37 to the bank each month. Find a formula that gives the balance B, in dollars, in the piggy bank after t months.arrow_forwardDecomposing Functions To join a book club, you pay an initial fee and then a fixed price each month for a book. The total cost in dollars of joining the club and buying n books is given by C=30+17n. What is the initial fee? What is the cost of each book after you are a club member?arrow_forwardTEST YOUR UNDERSTADING FOR EXAMPLE 3.5 A donation to the university is required for the privilege of purchasing premium season football passes. The cost is a linear function of the number of season passes. It costs 8000 to get season passes for myself and my spouse. To get passes for my entire family of 5, it costs 17,000. Use a formula to express the total cost C, in dollars, of n season passes. EXAMPLE 3.5 CHANGING CELSIUS TO FAHRENHEIT Temperature F=F(C) in Fahrenheit is a linear function of the temperature C in Celsius. A lab assistant placed a Fahrenheit thermometer beside a Celsius thermometer and observed the following: When the Celsius thermometer reads 30 degree (C=30), the Fahrenheit thermometer reads 86 degrees (F=86). When the Celsius thermometer reads 40 degrees, the Fahrenheit thermometer reads 104 degrees. Part 1 Use a formula to express F as a linear function of C. Part 2 At sea level, water boils at 212 degrees Fahrenheit. What temperature in degrees Celsius makes water boil? Part 3 Explain in practical terms what the slope means in this setting.arrow_forward
