Write an equation that represents the relationship.

Step-by-step explanation:

Given that neighbour's price, n, of buying honey that has a regular price, r, an equation can be written from the tables given to represent the relationship.

From the table above, you would observed that for each neighbor's price given, there is a particular discount. In other words, the difference between the neighbor's price and the regular price is same for each price relationship represented on the table.

Thus,

n = r - 2.5

For example, in the first case, instead if paying $7 as regular price of honey, Khalid gives a discount of $2.5, to his neighbor. The neighbor pays $4.50 dollars instead of the regular price of $7.

Same applies to all price relationship represented on the table.

An equation that represents the relationship is
