Answer:
[tex]f(n)=0.75n-0.50[/tex]
Step-by-step explanation:
We are given that
Cost of one can of noodle soup=$0.75
You have a coupon =$0.50 off on your total purchase.
We have to find the function rule for the cost of n cans of soup.
To find the function rule for the cost of n cans of soup we will find first cost of n cans of soup without coupon.
Multiply 0.75 by n to get the cost of n cans of soup
Cost of n cans of soup =[tex]0.75\times n[/tex]
Cost of n cans of soup =[tex]0.75n[/tex]
Now, subtract $0.50 from total cost of n cans of soup because coupon of $0.50 off on total purchase
Therefore,exact cost of n cans of soup,f(n)=[tex]0.75n-0.50[/tex]
Where f(n)=Total cost of n cans of soup
Hence, the function rule for the cost of n cans of soup=[tex]f(n)=0.75n-0.50[/tex]
