Amount of water collected on a month = 8.4 gallons
Amount of water used in garden = 5.2 gallons
Amount of water used in flowers = 6.5 gallons
Total amount of water used up = 5.2 + 6.5 = 11.7 gallons
Dat gurl saved 8.4 gallons in that month & she used up 11.7 gallons water. So, the rainwater supply was decreased by (11.7 - 8.4) = 3.3 gallons
