Answer:
B. Let n = the number of DVDs rented; 20 + 4n = 6n; 10 videos
Step-by-step explanation:
Let n = number of DVDs to rent
Movie Mania = 20 + 4n
Hurricane = 6n
Equate the cost of renting a DVD in both stores
Movie Mania = Hurricane
20 + 4n = 6n
20 = 6n - 4n
20 = 2n
Divide both sides by 2
n = 20 / 2
= 10
n = 10
The correct answer is
B. Let n = the number of DVDs rented; 20 + 4n = 6n; 10 videos
