Answer to Problem 59AYU
Solution:
a) The function f can be defined as
Explanation of Solution
Given:
It is given that the U.S. Postal Service charged $0.98 postage for first-class mail retail flats weighing up to 1 ounce, plus $0.22 for each additional ounce up to 13 ounces.
- Let the first-class postage charged, for a flat weighing 13 ounces.
Upto 1 ounce, $0.98.
1-2 ounce 0.98+0.22 = $1.2
2-3 ounce 1.2+0.22 = $1.42
3-4 ounce 1.42+0.22 = $1.64
4-5 ounce 1.64+0.22 = $1.86
5-6 ounce 1.86+0.22 = $2.08
6-7 ounce 2.08+0.22 = $2.3
7-8 ounce 2.3+0.22 = $2.52
8-9 ounce 2.52+0.22 = $2.74
9-10 ounce 2.74+0.22 = $2.96
10-11 ounce 2.96+0.22 = $3.18
11-12 ounce 3.18+0.22 = $3.4
12-13 ounce 3.4+0.22 = $3.62
First-class rates do not apply to flats weighing more than 13 ounces.
The function can be defined as,
To find: b) Graph of the function C .
