The correct answer is D. An increase in quantity demand as price decreases
Step-by-step explanation:
The graph shows the relationship between price (amount of money to get a product) and demand (quantity of a product consumers are willing to buy). The price of the product is shown in the Y or vertical axis, while the demand is shown in the X or horizontal axis.
Additionally, as the price decreases the demand increases; for example, at the beginning the price is $15.00 and the demand is 0; later when the price is $10.00 the demand increases to 20; and finally, when the price is almost $2.50 the demand is around 45.
This shows the two factors have a negative correlation because as the price decrease the quantity demand increases (Option D), which occurs because at lower prices people more people are willing to afford the product.
