Noah thinks the answers to these two questions will be the same.

*This year, a herd of bison had a 10% increase in population. If there were 550 bison in the herd last year, how many are in the herd this year?

* This year, another herd of bison had a 10% decrease in population. If there are 550 bison in the herd this year, how many bison were there last year?


Do you agree with him? Select the best explanation.

Yes, in both questions the percent change was the same amount and the initial totals were the same amount also.

No, in both questions the percent change was the same amount but they are different herds.

Yes, even though the first herd size increased and the second herd size decreased they both ended up with 550 bison.

No, the first herd size increased and the second herd size decreased and both started with 550 bison, so herd 1 is bigger than herd 2.
