Question

Write a function rule.

Answer 1

The correct answer option is A. C(n) = 0.75n - 0.50.

Explanation:

We are given that a soup noodle costs for $0.75 per can and that we can get $0.50 off your total purchase.

So the cost of n cans of noodle soup will cost = 0.75 × n = $0.75n

And since we can have a discount of $0.50 from the total purchase, despite of how many cans are purchased, the function for the cost of n cans of soup will be C(n) = 0.75n - 0.50.

Answer 2

The function becomes

C (n) = 0.75n - 0.50

Explanation:

As given

Suppose a noodle soups is on sale for $0.75 and have a coupon off $0.50 of total purchase .

Cost for n cups of soups = 0.75n

Total cost for n cups of soups = Cost for n cups of soups - Coupon off amount

Thus the function becomes for n cups of soup.

C (n) = 0.75n - 0.50
