Part A What is the rate of change of the shipping cost, in dollars per
pound of weight?
Enter your answer in the box.
To ship a package, a company charges a one-time fee plus a
fee based on the weight of the package. This table shows the
total shipping costs for four packages of different weights.
Shipping Costs
Weight of Package Total Shipping Cost
(pounds)
(dollars)
4
$11.00
8
$17.00
$23.00
16
$29.00
Part B
Which equation represents the total shipping cost, C, in
dollars, of a package weighing w pounds?
12
O A. C = 4.0w + 6
B. C= 2.5w + 1
C. C= 1.5w + 5
D. C = 1.5w + 4

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
