Q:

A) decrease | B) stay the same |

C) increase four fold | D) increase to more than double |

Answer & Explanation
Answer: D) increase to more than double

Explanation:

Explanation:

The best approach is to pick a number that satisfies the rules that x and y are greater than 0. So for example you could choose 25 for y.

The value of x before doubling is then 25 - 50/25 = 23

The value after doubling y will be 50 - 50/50 = 49, which is more than double.
