Answer:
The answer to you question is months 4 and 5
Explanation:
To solve this problem get the slope of the different intervals
2-3 Months m = (80 - 110) / (3 - 2)
= -30 / 1
= -30
3 - 4 Months m = (50 - 80) / (4 - 1)
= -30 / 1
= -30
4 - 5 Months m = (90 - 50) / (5 - 1)
= 40 / 1
= 40
5 -6 Months m = (110- 90) / (6 - 5)
= 20 / 1
= 20
Conclusion
The greatest change was between the months 4 and 5
