Answer: Brady sprayed 11 quarts of fertilizer

Then, 3 gallons = [tex]4\times3=12\ \text{ quarts}[/tex]
After he finishes spraying the lawn he has 1 quart of fertilizer left over.
Then, the number of quarts of fertilizer Brady sprayed on the lawn
= Quarts of fertilizer bought - Quarts of fertilizer left
=12-1=11 quarts
Hence, Brady sprayed 11 quarts of fertilizer .
