Question

2. Suppose that the function F(x)=2x12 represents the cost to rent x movies a month from an internet movie club. Kayla now has $10. How many more dollars does she need to rent movies

Answer 1

EXPLANATION

Given the function 2x+12 and the variable x that represents the number of movies.

Kayla has $10.

In order to rent more movies, we can apply the following algebraic expression to get the solution:

If she needs to rent 7 movies, she would has:

2*7+12 = 2+12 = 14+12 = 26 dollars

So, she need 26 dollars - 10 dollars(Available) = $16.00

Hence, Kayla needs $16 more dollars to rent 7 movies.
