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.
