#69 does not specify that Harry is reselling the desk. Needs clarification.
#70 is incorrect. If y=0, then x can be more than 3. Must specify as integers for the answer to be A.
#74 is mess. If x=y+1 and x and y are integers, they must be consecutive integers. x+y is supposed to equal 72, but consecutive integers cannot sum to an even number. If x and y have the same tens digit, they could be 34 and 38 or 36 and 36, but both of those have a different x*y.
Worked through 81 so far.
