4/15=x/75
4*75=15*x
300=15x
x=300/15
x=20
200x 9, nine times two hundred,
The answer would be (n+7)5
hope this helps
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.
