There are in total 3600 cases of chickenpox by week 20.
A word problem is a math issue that has been expressed as a scene from a tale. It basically asks you to picture how you would use arithmetic to solve a real-world situation. It is a mathematical problem expressed entirely in words typically used as an educational tool.
Given that,
Documented cases = 32
Outbreak spread = 80% per month = 0.8
Outbreak spread per week = 0.2
Total documented cases by the week 20 = 20*0.2 +32 = 36*100 = 3600
Thus, there are in total 3600 cases of chickenpox by week 20.
