35. Mrs. Frasier is making costumes for the school play. The table shows the amount of material needed for each

complete costume. She bought yards of material.

a. How many complete costumes can she make? How much material will be left over? b. If she spent a total of $44.25 on fabric, what was the cost per yard? Explain how you solved.

SOLUTION: a. To find the amount of material needed for a complete costume, add the amounts needed for a top and bottom.

So, one complete costume requires yards of material.

To find the number of costumes Mrs. Frasier can make, divide the yards she bought by the amount of material

required for each costume. Write as .

So, Mrs. Frasier can make 8 complete costumes with some material left over for of a costume. To find how

much material will be left over, multiply by the amount of material needed for one complete costume.

So, there will be yard left over.

b. To find the cost per yard, divide the total cost by the number of yards purchased.

So, the cost per yard was $3.

36. Financial Literacy The value of a certain stock increased by %. Write the percent as a fraction in simplest

form.

SOLUTION:

37. A high school Family and Consumer Science class has pounds of flour with which to make soft taco shells.

There are cups of flour in a pound, and it takes about cup of flour per shell. How many soft taco shells can

they make?

SOLUTION: Convert the amount of flour that the class has from pounds to cups.

So, the class has cups of flour.

To find how many soft tacos the class can make, divide the total amount of flour by the amount of flour needed for one shell.

So, the class can make about 140 soft taco shells.

38. Emma runs mile in 6 minutes. Joanie runs miles in 11 minutes. Whose speed is greater? Explain.

SOLUTION: Find Emma's rate by dividing the number of miles she ran by the number of minutes.

So, Emma's rate is 0.125 miles per minute. Find Joanie's rate by dividing the number of miles she ran by the number of minutes.

So, Joanie's rate is about 0.136 miles per minute. Joanie's speed is greater since 0.136 > 0.125.

39. Financial Literacy A bank is offering home loans at an interest rate of %. Write the percent as a fraction in

48. Persevere with Problems A motorized scooter has tires with circumference of 22 inches. The tires make one

revolution every second. Find the speed of the scooter in inches per second. (Hint: The speed of an object

spinning in a circle is equal to the circumference divided by the time it takes to complete one revolution.)

SOLUTION: To find the speed of the scooter, divide the circumference by the time it takes to complete one revolution.

So, the speed of the scooter is 220 inches per second.

49. Building on the Essential Question Explain how complex fractions can be used to solve problems involving ratios.

SOLUTION: Students should recognize that complex fractions are fractions with a numerator, denominator, or both that are also fractions. So, if one of the numbers in the ratio is a fraction, then the ratio can be a complex fraction.

50. Debra can run miles in hours. How many miles per hour can she run?

A miles per hour

B miles per hour

C miles per hour

D miles per hour

SOLUTION:

To find the number of miles Debra can run per hour, divide 20 miles by 2 hours. Write 20 as and 2 as .

Since Debra can run 9 miles per hour, D is the answer.

51. Tina wants to give away 6 bundles of thyme from her garden. If she has pound of thyme, how much will each

bundle weigh?
