Question

1. Lucy has a jewelry business. To make a certain necklace, she spends $3.38 on materials and $5.57 on labor. She then sells the necklace for $15.99. Lucy’s profit on the necklace is equal to the sale price minus the cost of materials and labor. (a) How much profit does Lucy earn when she sells a necklace? What fraction of the sale price of the necklace is profit? Record your answer as a fraction using whole numbers. (b) What decimal of every dollar of the sale price of the necklace is profit? Show your work. Round your answer to the nearest hundredth. (c) Lucy collected $223.86 selling necklaces at a craft fair. How many necklaces did Lucy sell? How much profit did she earn? Show your work.

Solution 1

A) Lucy earns 7.04

B)3.38+5.57=8.95 to-> to the nearest hundred $9

C) Lucy sold 15 collars at the fair.

I hope this helps, not sure about my answer on letter B.

Question

What is the equation for this word problem: When a tow truck is called, the cost of the service is $10 plus $1 per mile that the car must be towed.

Solution 1

The equation is 10 + 1x =y

Solution 2

10+(1*x)=

The X represents the number of miles the car must be towed

The X represents the number of miles the car must be towed

Question

A ratio compares two values using which operation? addition subtraction multiplication division

Solution 1

**Answer:**

A ratio compares two values using division operation

**Step-by-step explanation:**

we know that

A ratio is a quantitative relation between two numbers

Let

x------> the first number

y------> the second number

The ratio between x and y is equal to

therefore

A ratio compares two values using division operation

Solution 2

A ratio is a fraction which is technically a division problem.

Question

happy paws charges $19.00 plus $1.50 per hour to keep a dog during the day.Woof Watchers charges $15.00 plus 2.75 per hour.Write and solve an equation to find for how many hours the total cost of the service is equal

Solution 1

1.50 * X + 19 = 2.75 * X + 15

just put a random number for X and you should be good to go

just put a random number for X and you should be good to go

Question

A delivery truck has 40,000 miles on its odometer and travels an average of 22,000 miles per year. Which function best models the linear relationship? y = 22,000x − 40,000 y = –22,000x + 40,000 y = 22,000x + 40,000 y = 40,000x − 22,000

Solution 1

The function that best models the** linear relationship** will be** y = 22,000x + 40,000.**

Let the number of years be represented by x.

From the information given, the **delivery truck **has 40,000 miles on its **odometer **and travels an average of 22,000 miles per year, this will then be;

y = 40000 + (22000 × x)

**y = 40000 + 22000x**

Therefore, the function that best models the **linear relationship** will be **y = 22,000x + 40,000.**

Solution 2

Well, y-intercept is what we start with(40000) and the slope is the rate of increase/decrease(22000).

Question

Estimate the unit rate to the nearest hundredth.
$1.19 per 12fl oz price of 1 fl oz

Solution 1

**Unit rate** is used in mathematics to compare *one quantity with another quantity.*

The **unit rate** to the nearest hundredth is **$0.010**

From the question, we know that __ 12 fl oz is $1.19.__ To find the

12 fl oz = $1.19

1 fl oz = ?

Cross Multiply

1 fl oz x $1.19 / 12 fl oz

= **$0.099166**

To the nearest hundredth, the unit rate is **$0.010**

Therefore, the unit rate to the nearest hundredth is **$0.010**

Solution 2

I believe the price of 1 fl oz. would be 0.09916667.

Question

In a box of pens, there are three times as many red pens as green pens and two times as many green pens as blue pens. For the pens in the box, write down the ratio of the number of red pens to the number of green pens to the number of blue pens.

Solution 1

The **ratio **of the numbers of red, green and blue **pens **is 3:1:2

A **ratio **is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that, In a box of **pens**, there are three times as many red **pens **as green **pens **and two times as many green pens as blue **pens**.

Let the number of green **pens **be x,

Then the number of red **pens **= 3x

Number of blue **pens **= 2x

Ratio = 3x:x:2x

= 3:1:2

Hence, the **ratio **of the numbers of red, green and blue **pens **is 3:1:2

Question

Given the slope and y-intercept can you write an equation for the line?

Solution 1

Y=mx+b

m=slope

b=yintercept

example

if slope=3

yintercept is 2 then

y=3x+2

simple as that

m=slope

b=yintercept

example

if slope=3

yintercept is 2 then

y=3x+2

simple as that

Solution 2

Yes, because the equation to find the proportional relationship is y=kx. Y- origin

K- constant rate of proportionality

K- constant rate of proportionality
