Makayla needs an additional $16 to rent 7 movies next month, based on the cost function f(x) = 2x + 12 and the fact that she currently has $10.
Step-by-step explanation:
The student has asked how many more dollars Makayla needs to rent 7 movies next month if the cost function for renting movies is f(x) = 2x + 12, where x represents the number of movies.
To find the cost for 7 movies, we substitute x with 7 in the equation:
f(7) = 2(7) + 12 = 14 + 12 = 26
Now, we know Makayla has $10. To find out how many more dollars she needs, we subtract the amount she has from the total cost:
$26 - $10 = $16
So, Makayla needs an additional $16 to rent 7 movies next month
The probable question can be: suppose that the function f(x)=2x+12 represents the cost to rent x movies a month from an internet movie club. makayla now has $10. how many more dollars does makayla need to rent 7 movies next month?
