Question

A movie rental company charges $3 per movie, m, and a monthly fee of $20. What is the equation that represents the cost, C, to rent movies from the company for one month

Answer 1

Answer:

c = 2m + 20

Step-by-step explanation:

Before anything, let's make sure our variables are defined:

Movie = M

Cost = C

A way to think about this is because we're looking for C and our M value is changing, C = y and M = x. That would make 20 = b, making this C = 3M + 20. (This may or may not make sense, so if it doesn't, just ignore this.)

Ok so the first thing to note is that this is for one month. What does that mean? That means, our $20 monthly fee never changes. It happens once in the equation. So whatever we have, we add $20 to it, once.

The second thing to note is that we don't know how many movies are being rented. But! We already have a variable m for how many movies are being charged. So to find the number of movies, we find $3 * m, or $3m.

Finally, we know how much the monthly fee is and we know how much the movies are, so we add those together to find the total cost:

c = 3m + 20

*Note: Your grader may or may not want $ signs next to each number. It is doubtful they would, and I've never seen it, but just in case, your actual answer would be: $(c = 2m + 20)

Answer 2

Answer:

3m + 20 = C
