Lee scored 25 points in yesterday's game. That was 3 more than twice the number of points Alex scored. Which equation can be used to find, a, the number of points Alex scored?A.2(25) = 3 + aB. 25 + 3 = 2aC.2(25) + 3 = aD. 25 = 3 + 2a

Question
Answer:
The answer to this is D.

The tricky part of this question is to determine the relationship between Lee's points and Alex's points.

From the description "Lee scored 25 points" we can be sure that Lee's points are 25. That's the easy part.

Here comes the real question. We need to change "that was 3 more than twice the number of points Alex scored" into an algebraic equation. From "twice the number of points Alex scored", we can know it's 2a, as Alex's points are represented by a and twice means 2 times. From "that's 3 more", we can determine that Lee has a higher point (25 larger than 2a by 3 points). So, Alex need to add a few more points in order to have the same value as Lee did.

Therefore, if we combine everything together, we can get 25 (Lee's points) = 3 + 2a (twice Alex's points plus 3 because Alex has less points). The answer is D.
