Question

1) Movie Checkout for the week Days 2 3 4 A. 10 How many movies were checked out on Day 1? Number of Movies 30 45 60 C. 20 B. 15 D. 25​

Answer 1

15 movies.

Subtract day 4 from day 3 and you get 15
Subtract day 3 from day 2 and you get 15

Every day fifteen more movies are sold that the last, so to find the first you would need to subtract day 2 by 15

30 - 15 = 15

This would only work if the graph is proportional, meaning the increase or decrease is the same for every day.

Answer 2

B. 15 because this is a ratio box
