Question

A group of scientists monitored the population of gypsy moths and the rate of defoliation in one US region over a four- year period. Their collected data appears in the chart. Study the data, and then answer the following questions. Population of Moths Acres of land with Defoliation Year 1 3,845 55,100 Year 2 5,780 125,460 Year 3 15,804 325,455 Year 4 52, 350 741,355 Part A Calculate the percent increase in population between year 1 and year 2, year 2 and year 3, and year 3 and year 4. Round up or down to the nearest whole percentage. Show your work.​

Answer 1

Percent increase between years 1 and 2:

(5,780 – 3,845) ÷ 3,845 = 0.50 = 50% increase

Percent increase between years 2 and 3:

(15,804 – 5,780) ÷ 5,780 = 1.73 = 173% increase

Percent increase between years 3 and 4:

(52,350 – 15,804) ÷ 15,804 = 2.31 = 231% increase

Answer 2

Percent increase between years 1 and 2:

(5,780 – 3,845) ÷ 3,845 = 0.50 = 50% increase

Percent increase between years 2 and 3:

(15,804 – 5,780) ÷ 5,780 = 1.73 = 173% increase

Percent increase between years 3 and 4:

(52,350 – 15,804) ÷ 15,804 = 2.31 = 231% increase
