1 is D, because if you wrote out all the choices as equations, you would get that A is 1/2 n - 3, B is also 1/2 n - 3, C is 1/2 - 3, and D is 1/2(n - 3)

2 is A, because 3 times her age minus 4 is 3x-4, with x as Marcys age

3 is C, because although 11 x 5 is 55, it says that 5 times a number is LESS than 55, so the answer is 10, or C

4 is B because the mode is 92, the mean is 122, and the median is 88, which would mean that mean>mode>median
