1 In Anchorage, the formula for Celsius is. Solve for F._________ Also, find out how much 2° Celsius is in Fahrenheit. _______________ F = 35.6

2 In Boston, the volume of an ice-cream cone at Boston Creamery is 45 cm 3. Find the diameter of the cone if the height is 8 cm. ________________ (You may use a calculat or for this one.) r = 2.32 d = (2)(2.32) = 4.64

3 A taxi-cab in Chicago charges $ 4 a mile plus a “starting fee” of $ 2. How far can Sally go if she only has $ 28? ______________ x = number of miles 4 x + 2 = 28 4 x = 26 x = 26 / 4 = 13 / 2 = 6.5 miles

4 Suppose that the function f (x) = 3 x + 12 represents the cost to rent x movies a month from an internet movie club in Denver. Makayla now has $ 10. How many more dollars does Makayla need to rent 9 movies next month? ________________ Cost to rent 9 movies: 3(9) + 12 = 27 + 12 = 39 Money needed: 39 – 10 = 29

5 In Evansville, a small pond was filling up by 2 gallons per 4 hours because of rainfall. If there were 28 gallons at 10:00 PM, how many gallons were there at 10:00 AM the next morning? ________________ From 10:00 PM to 10:00 AM is 12 hours. 4 x = 24 x = 6 At 10:00 AM, ther would be 28 + 6 = 34 gal.

6 Sally and her dad live in Fort Worth. Her dad is five times her age. Their combined age is 50. How old is her dad? _______________ x = Sally’s age 5 x = dad’s age x + 5 x = 50 6 x = 50 x = 50 / 6 = 25 / 3 = 8 1 / 3 years dad’s age = 5 (8 1 / 3 ) = 40 1 / 3 years

7 Suppose that the hidden formula for Coca-Cola in Atlanta is Solve for m. _______________

8 In Honolulu, a school purchases boxes Of candy bars. Each box contains 40 bars. Each box costs $ 20. How much does the school have to charge for each candy bar to make a profit of $ 10 per box? _______________ x = cost of one bar 40 x = 30x = ¾ dollars = $.75

9 In Indianapolis, Jane is selling lemonade. She had to pay $ 10 in supplies. She makes $ 1.50 per glass of lemonade. How much does she have to sell to make $ 20? _______________ x = number of glasses 1.5 x – 10 = 20 1.5 x = 30 15 x = 300 x = 20

10 In Jacksonville, the perimeter of a rectangular park is 1 mile (5280 feet). the length is 240 feet more than three times the width. Find the length of the park. _______________ x = width 3 x + 240 = length 2 l + 2 w = perimeter 2(3 x + 240) + 2 x = 5280 6 x + 480 + 2 x = 5280 8 x + 480 = 5280 8 x = 4800 x = 600 3 (600) + 240 = length = 1800 + 240 = 2040

11 In Knoxville, the volume of a can of Kdrink is 20 in 3. Find the height of the can if the diameter of the can is 8 inches. (V = π r 2 h) a. Solve for h. ___________ b.Show what you are substituting into the equation. c.Round your answer to the nearest tenth. _______________ (You may use a calculator for this one.) h =.398

12 In Las Vegas, Nancy buys a case of 24 waters for $ 6. How much does she have to sell each water for if she wants to make a profit of $ 0.75 for each bottle of water? ______________ Total profit desired for 24 waters: 24 $.75 = $ 18 x = cost per water 24 x = 6 + 18 = 24 24 x = 24 x = $ 1.00

13 In Miami, the total cost of three books plus $ 2.50 shipping is $ 38.50. What would the cost of five books and shipping be? (Assume that the shipping would be the same basic cost.) ______________ x = cost of one book 3 x + $2.50 = $ 38.50 3 x = $ 36 x = $ 12 Cost for 5 books = 5(12) + 2.50 = 60 + 2.50 = 62.50

14 In Nowhere, 3 (x + 2) = 10. What is 2 x – 5? _______________ 3 x + 6 = 10 3 x = 4 x = 4 / 3 2 ( 4 / 3 ) – 5 = 8 / 3 – 5 = 8 / 3 – 15 / 3 = - 7 / 3 = - 2 1 / 3
