Question

Abigail and Seth are playing a card game. Abby's score is 268 points

less than Seth's score. Seth's score is 654. Which is the best Abbys
estimate of Abigail's score?
a) 500
c) 400
b) 300
d) 600

Answer 1

400

Explanation:

If Seth's score is 654 and Abigail's score is 268 less than Seth's score, then Abigail's score can be found by subtracting 268 from 654:

Abigail's score = 654 - 268 = 386

Therefore, the best estimate of Abigail's score is closest to 400, which is answer choice (c).

Answer 2

Answer: c) 400

Explanation:

If Seth's score is 654, we will round it to 650. If Abby's score is 268 points, we will round it to 250.

Then, we will subtract; 650 - 250 = 400

When we do the "actual" math, we see that 654 - 268 = 386, so 400 is the closest estimate.
