Question

You are buying orange juice for $4.50 per container and have a gift card worth $7. The function f(x)=4.50x-7 represents your total cost f(x) if you buy x containers of orange juice and use the gift card. How much do you pay to buy 4 containers of orange juice.

your answers will be 11 dollers

Explanation:

Answer 2

The function
`f(x)=4.50x-7` gives the total cost ( f(x) ) of x containers of orange juice (with a $7 gift card).

We want to buy 4 containers, so we plug in 4 into x and find the value of f(x).

`f(x)=4.50(4)-7\\=18-7\\=11`.

You will have to pay $11 in total.

ANSWER: $11
