Alex Ar [27]

Answer:

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

We have to create a table to show the relationship between the number of scarves x and the cost 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

Truck A costs $600 more that Truck B. However, it burns 0.06 gallon/mile compared to 0.07 gallon/mile for truck B. Both trucks h
qwelly [4]

Answer:

  1,778

Step-by-step explanation:

Let C and S represent the cost and salvage value of Truck B, respectively. Let X represent the number of miles per year that answers the question.

Truck A's cost for 10 years is ...

  A = C+600 +(0.06)(2.25)(10X) -(S+200)

Truck B's cost for 10 years is ...

  B = C +(0.07)(2.25)(10X) -S

We want to find X such that Truck A's cost is lower, so ...

  C -S +1.35X +400 < C -S +1.575X

  400 < 0.225X

  1777 7/9 < X

1778 miles driven per year (or more) makes Truck A a better option.
