Jenna knits scarves and then sells them on Etsy, an online marketplace. Let C(x) = 4x + 20 represent the cost C in

tia_tia [17]

Answer:

Domain of C={1,2,3,4,5,6}

Range of C={24,28,32,36,40,44}

Step-by-step explanation:

We are given that Jenna knits scarves and sells them on Etsy an online market place.

$C(x)=4x+20$

Where C=Represents the cost in dollars

x=Number of scarves produced.

We have to find the domain and range of C.

Substitute x=1

$C(1)=4(1)+20=$ $24

Substitute x=2

$C(2)=4(2)+20=$ $28

$C(3)=4(3)+20=$ $32

$C(4)=4(4)+20=$ $36

$C(5)=4(5)+20=$ $40

$C(6)=4(6)+20=$ $44

Therefore, Domain of C={1,2,3,4,5,6}

Range of C={24,28,32,36,40,44}

If a canoe travels with a speed of A mph for 3 hours, and then with a speed of B mph for the rest of the journey, how long does

mylen [45]

For time-speed-distance problems, you use the relationship
.. speed = distance/time
in any of its various forms.

The distance traveled at A mph is
.. distance = speed * time
.. distance = A*3

The time required for the rest of the journey is
.. time = distance / speed
.. time = (C -3A)/B

The the total time required to travel C miles is the 3 hours for the first part plus the time for the rest of the journey.
.. total journey time = 3 + (C -3A)B . . . . . hours
