Question

A video store charges $4 to rent the first movie and x for each additional movie. What expression would represent the cost for renting 5 movies?

Answer 1

Since it costs $4 to rent the first movie, and $X for each additional movie, the correct equation is y=4x+4.
The reason it's 4x instead of 5x is because the first movie costs $4, and the remaining 4 movies cost $X each.
