    Read the question once more, then think about it.

    Yes. The next time you come across a question like this, what you should do is use actual values to test out the equation. For example, suppose Ted had 1 dollar and 1 quarter. If that's the case then he should have $1.25 in his pocket. You think 1 + 0.25q is correct so test it: Let q = 1, then 1 + 0.25q = 1 + 0.25(1) = 1 + 0.25 = 1.25 Suppose he had 1 dollar and 2 quarters in his pocket. Then he should have $1.50. Testing that: 1 + 0.25q = 1 + 0.25(2) = 1 + 0.50 = 1.50 If you keep going, you'd realize option B is the only option that gives the correct result every time.
