Question

A video rental store charges a $20 membership fee and $2.50 for each video rented.

Write a linear equation to model this situation.

Tell what each variable represents.

Answer 1

2.5x + 20 = y

Explanation:

first, assign a variable to each unknown:

since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y

x = number of videos rented

y = total cost

so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.

So, the equation is 2.5x + 20 = y

Answer 2

Y=2.5x +20 because x would be the number of times you go, and 20 dollars is the original price
