Victoria is putting down fertilizer in her garden. for every 25 square feet of garden, she needs one pound of fertilizer. let p represent the number of pounds of fertilizer. let g represent the area, in square feet, of garden she covers. which correctly names the independent and dependent variables?

Let's sample some data in order to find a pattern. With 25 square feet of garden, you need 1 pound of fertilizer, so we have the first couple:

If the garden is twice as big, i.e. 50 square feet, you need twice as much fertilizer, i.e. 2 pounds:

...and similarly for a garden three times as big:

Can you see the pattern? The value of g is always 25 times the value of p. Once the pattern is discovered, we only need to write it down in formula instead of words:
