Answer:
<h2>The cost increases $3.99 for every additional movie rented.</h2>
Step-by-step explanation:
In this situation, the rate of change means the cost per movie.
Specifically, the cost is $3.99 per movie. In other words, the cost increases $3.99 when the number of movies increases by 1.
We could also say it like the cost increases $3.99 for every additional movie.
Therefore, among the options the second choice is correct, because specifies the right ratio of change that the table shows.
You can get this ratio of change by subtracting $7.98 - $3.99 = $3.99. Then, if you sum this difference to $7.98, you would get $11.97, and then $15.96, and so on. That means the ratio of change is $3.99 per movie.
