Netta bought n shirts from the Walmart. Walmart charges $9 per shirt. Later the same day, netta bought n more shirts from amazon

Ipatiy [6.2K]

Answer:

$T(n)= 17n + 5$

Step-by-step explanation:

We are given the following in the question:

Number of shirts bought from Walmart = n

Cost of one shirt at Walmart = $9 per shirt

Total cost of shirt at Walmart =

$=\text{Number of shirts}\times \text{unit cost}\\=9n$

Number of shirts bought from Amazon = n

Cost of one shirt at Amazon = $8 per shirt

Shipping fee for entire order = $5

Total cost of shirt at Amazon =

$=\text{Shipping fee} + (\text{Number of shirts}\times \text{unit cost})\\=5 + 8n$

Total amount spent by Netta on shirts in one day =

Total cost of shirt at Walmart + Total cost of shirt at Amazon

$T(n)= (9n) + (5+8n)\\T(n)=9n + 8n + 5\\T(n)=17n + 5$

is the required expression where T(n) is the total cost and n is the number of shirts purchased at Walmart as well as Amazon.

Students attending the University of Florida can select from 130 major areas of study. A student's major is identified in the re

omeli [17]

Answer:

1. 8385 double majors

2. 18252 major codes

3. 8515 codes

4. Yes

Step-by-step explanation:

Given

Major areas = 130

Alphabets = 26

There are 130 major areas in the university.

To get a double majors, means one select any of two of the major areas in the university.

i.e. just 2 alphabets are needed

Number of Double Majors = 130C2

130C2 = 130!/(128!*2!)

130C2 = 130 * 129/2

130C2 = 8385.

Number of major codes available = Number of 2 digit codes + Number of 3 digit codes

Number of 2 digit codes = 2 alphabets

There are 26 ways of selecting the first letter

There are 26 ways of selecting the second letter

So, number of 2 digit codes = 26 * 26 = 676.

Number of 3 digit codes = 3 alphabets

There are 26 ways of selecting the first letter

There are 26 ways of selecting the second letter

There are 26 ways of selecting the third letter

So, number of 3 digit codes = 26 * 26 * 26 = 17576

Thus, number of major codes = 17576 + 676 = 18252

Number of codes to identify a student with either a single major or double major

Number off single major codes = number of major areas = 130

Number of double major codes = 8385

Total = 130 + 8385 = 8515

d. From the solutions above, Yes there are enough codes available to identify all single and double majors at the university
