Answer:

The equation representing pounds of apples will has left x=20-4-6-3.

Will has left with 7 pounds of apples.

Step-by-step explanation:

Given:

Total pounds of apple = 20 pounds.

Pounds of apple used for apple sauce = 4 pounds

So we can say that;

pounds of apples will has left can be calculated by subtracting Pounds of apple used for apple sauce and Pounds of apple used for apple butter and Pounds of apple used for making juice from Total pounds of apple.

framing in equation form we get;

x=20-4-6-3

Hence The equation representing pounds of apples will has left x=20-4-6-3.

On Solving the above equation we get;

x=7\ pounds

Hence Will has left with 7 pounds of apples.
