To find out how much cheddar cheese the cheese maker has left, you need to subtract the amount sold from the original amount made.
Original amount of cheddar cheese: 96.639 ounces
Amount sold: 91.705 ounces
Now, perform the subtraction:
\( 96.639 - 91.705 = 4.934 \)
So, the cheese maker has 4.934 ounces of cheddar cheese left.
