Does a proportional relationship exist? Find the constant rate of change & interpret its meaning. A. Yes, Every 1 day, sales increase by $1000
B. Yes, Every 3 days, sales increase by $1000
C. No, Every 2 days, sales increase by $500
D No. Every 3 day, sales increase by $30

B. Yes, Every 3 days, sales increase by $1000

Step-by-step explanation:

A proportional relationship exists because the line cuts across the point of origin, (0, 0).

Constant rate of change is that there is an equal sales increase of $1,000 on every 3 days. Thus, on day 3, sales was $1,000. On day 6, sales was $2,000.

This shows proportional increase of $1,000 of sales, every 3 days.
