Suppose noodle soup is on sale for $0.75 a can, and you have a coupon for $0.50 off your total purchase. write a function rule for the cost of n cans of soup

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 =

Cost of n cans of soup =

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)=

Where f(n)=Total cost of n cans of soup

Hence, the function rule for the cost of n cans of soup=
