Answer 1

If my bill is not expensive. I did not use my cell phone too much

Explanation:

Answer 2

Answer: "If my bill is not expensive. I did not use my cell phone too much"

Reason:

The original statement is of the form "If P, then Q"

P = "I use my cell phone too much"

Q = "my bill will be expensive"

An equivalent form to the original condition is known as the contrapositive of the form "If not Q, then not P". We swap the positions of P and Q. We also negate each part. You can use a logical truth table to verify that the conditional and contrapositive have equivalent truth values, which means they are effectively equivalent statements.
