Question

The Cincinnati zoo had 25 snakes before the Columbus zoo gave them 5 more. What is the percent increase from the 25 snakes?

Answer 1

This is a 20% increase. If we divvy up the 25 into 5 groups, we can say that each group is 20%. since we added another group of 5, we can go off of our known values and say that this was a 20% increase.
