Two insect colonies start out with the same populations but have different growth rates. Compare the colonies by finding and interpreting the average rates of change from week 10 to week 15

• Colony A increased by 1029 per week while Colony B increased by 475 per week

• Colony A increased by 20,615 per week while Colony B increased by 10,091 per week

• Colony B increased at a much faster rate, but we cannot determine the exact values

• Colony B increased by 5,146 per week while Colony B increased by 2,375 per week
