Amount of liquid plant fertilizer in the container that the gardener has = 6 1/5 pounds = 31/5 pounds We already know that 1 pound = 16 ounce Then Amount of liquid plant fertilizer in the container that the gardener has = (31/5) * 16 ounce = 496/5 pounds Amount of liquid plant fertilizer that the gardener uses on Sunday = 2 1/2 ounces = 5/2 ounces Then The amount of liquid plant fertilizer that are left= (496/5) - (5/2) ounces = (992 - 25)/10 ounces = 967/10 ounces = 96.7 ounces So the total amount of liquid plant fertilizer left is 96.7 ounces.
