Question

For #6, the cost to ship a first class package with the USPS is a
function of weight (in ounces) as follows:
$2.07,
((M) = {82.07 + 0.17 W
- 3),
0 3 < w < 13
6) How much will it cost to ship a 10 ounce package? (3 pts)
(A) $3.26
(B) $3.77
(C) $5.84
(D) $4.14

Answer 1

We have the next function that represents the cost to ship a first class package with the USPS in terms of weight (in ounces)

$c(w)=\begin{cases}\text{ \ }2.07,\ldots0And we must find the cost to ship a 10 ounce package.

Since is a 10 ounce package w = 10.

Now, if w = 10 we must replace the value in the second part of the function

[tex]\text{\ }2.07+0.17(w-3),w=10$

Now, replacing w = 10 we obtain

$\begin{gathered} \text{\ }2.07+0.17(10-3) \\ =\text{\ }2.07+0.17(7) \\ =\text{\ }2.07+1.19 \\ =\text{\ 3}.26 \end{gathered}$

So, ship a 10 ounce package will cost $3.26

ANSWER:

(A) $3.26
