You already owe $4.32 in overdue rental fees and are returning a movie that is 4 days late. Now you owe $6.48. Define a variable. Then write and solve an equation to find the daily fine for an overdue movie.

Variable = cost per day = x

I'll do this question two ways

Harder Algebra way

6.48 : 4 = x

multiply both sides by 4

6.48 = 4x

divide both sides by 4

1.62 = x

Easy non Algebra way

6.48 : 4 = x

6.48 : 4 = 1.62

so 1.62 = x

my equation is probably not how the teacher wants it but it's how I would do it so ...
