Each one can answer 17m questions in m minutes.
The total they can answer is 17m + 17m = 34m.
Every expression that is equal to 34m represents the amount they can both answer in the same number of minutes.
The expression we are looking for does not equal 34m.
a: 17m + m = 18m
b: 34m = 34m
c: 2(17m) = 34m
d: 17m + 17m = 34m
