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=

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
