Question

Katelyn can complete 17 integer questions in one minute. Collin can also complete 17 integer questions in one minute. Which expression does NOT represent the total amount integer questions Katelyn and Collin could complete if they both work for the same amount of minutes?

a: 17m + m
b: 34m
c: 2(17m)
d: 17m + 17m

Answer 1

a: 17m + m

Explanation:

Each one can answer 17 questions in 1 minute.

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

Only choice a does not equal 34m.

Answer: a: 17m + m
