A scientist is observing two ant colonies. The colonies each have 800 ants when he begins observing them. The population of Colony A increases by 25% each week. The population of Colony B decreases by 25% each week.
In each equation, y represents the ant population with respect to a number of weeks, x.
Drag each equation to show whether it can be used to represent the ant population of
Colony A, Colony B, or neither of these.
