What is 32 = 3.2c so what is the letter c

Whatever you do to one side, you have to do to the other.
32=3.2c
We need c by itself, so we need to divide both sides by 3.2.
32/3.2=10
C=10
Let’s make sure c equals ten by putting in ten for c.
3.2(10)=32
32=32
C=10

Well if you have 20 bats you probably want 20 balls? you don’t have enough context to answer the question.
