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

Answer 1

The function rule for the cost of n cans of noodle soup can be written as:

Cost(n) = (0.75 * n) - 0.50

Where:
- n represents the number of cans of soup.
- Cost(n) represents the total cost of n cans of noodle soup after applying the coupon.
