a²+ b² = c² is the formula for pythagorean theorem.
it is used to find out the hypotenuse(the side opposite the 90° angle) of a right angled triangle.
the two sides adjacent to the 90° angles are 'a' and 'c'. the theory is that if you add the squares of a and b, the hypotenuse is equal to c².

Step-by-step explanation:
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.
