Answer:
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](https://tex.z-dn.net/?f=%3D%5Ctext%7BNumber%20of%20shirts%7D%5Ctimes%20%5Ctext%7Bunit%20cost%7D%5C%5C%3D9n)
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](https://tex.z-dn.net/?f=%3D%5Ctext%7BShipping%20fee%7D%20%2B%20%28%5Ctext%7BNumber%20of%20shirts%7D%5Ctimes%20%5Ctext%7Bunit%20cost%7D%29%5C%5C%3D5%20%2B%208n)
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](https://tex.z-dn.net/?f=T%28n%29%3D%20%289n%29%20%2B%20%285%2B8n%29%5C%5CT%28n%29%3D9n%20%2B%208n%20%2B%205%5C%5CT%28n%29%3D17n%20%2B%205)
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.
