Fiona is mixing fertilizer with peat moss to add to her garden. The amount of fertilizer is proportional to the amount of peat moss. Each 12 -lb bag of peat moss costs $4 Which equation shows the relationship between the number of pounds of peat moss Fiona buys, p, and her cost in dollars, c?

Proportional graphs are used to represent graphs that have a constant rate.

The equation that shows the proportional relationship is

From the question, we have:

12 lb bag costs $4

Represent cost with c, and the weight of the bag with p.

So, the given parameter can be represented using the following ratio

Express as fraction

Multiply both sides by c

Hence, the equation that shows the relationship is
