Answer:
3rd one
Step-by-step explanation:
1,649 inches is the answer
3 * 2 ^ 2 < 16 + 5
should be performed in the order PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)/
Therefore, obtain
3 * 2 ^ 2 < 16 + 5
3 * 4 < 16 + 5 Exponentiation first
12 < 16 + 5 Multiplication second
Similarly, obtain
100 / 10 * 2 > 15 - 3
100 / 20 > 15 - 3 Multip[lication first
5 > 15 - 3 Division second
You want to isolate C, so the first step would to have it be positive. You would do this by adding C to both sides of the equation to cancel the C on one of the sides out like this:

. Then you want to cancel out the P, so you subtract it on both sides like this:

And that is your answer
