So we want to know what x times 2 is. So think about this: multiply x with 2. We can find out what works and what doesn’t. So remind yourself that if you are multiplying a negative number, you get a negative. And when you minus a negative with a positive it’s the same as a negative + a negative. So it can’t be a negative as the answer is 0. Try each positive and you will find the answer to be
X=8

50%, because to exceed is to be larger than, so if A is larger than B by 50%, then that means that B is 50% smaller than A.
mike charges 100 dollars service charge plus 65 dollars per hour.
amy charges 40 dollars service charge plus 80 dollars per hour.
the cost to repair from mike is 100 + 65 * x.
the cost to repair from amy is 40 + 80 * x.
let x = 3 and you get:
the cost to repair from mike is 100 + 65 * 3 = 295 dollars.
the cost to repaid from amy is 40 + 80 * 3 = 280 dollars.
as long as the time to repair is 3 hours or less, the cost to repair will be cheaper from amy.
