@w.timora, which choice do you think is correct?
@hero the last one
How much is a quarter worth?
How do you write 25 cent in decimal form?
ok so so it has to be one answer with 0.25
how do I figure that out?
Read the question once more, then think about it.
is it the second one?
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.
@hero Thank you so much!
