Answer:
15 rentals
Explanation:
Latest Releases Depot
rent = $3 per DVD
membership= free
let the number of DVD be x
let the expression for the total be
y= 3x----------------1
Video for You
rent= $2 per DVD
membership= $15
let the number of DVD be x
let the expression for the total be
y= 15+2x----------------2
equate 1 and 2
3x=15+2x
collect like terms
3x-2x=15
x= 15
Hence the number of DVDs needed for the two rentals to have the same amount is at least 15 rentals
