Answer 1

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.
