Answer:
number of people who will purchase next month = 250
the number of people who will purchase in 2 month = 325
Step-by-step explanation:
Data provided in the question:
people who purchase the plant's product during any month will not purchase it the next month = 30%
therefore, people who purchase the plant's product during any month will purchase next month = 70%
people who do not purchase the product during any month will purchase it the next month = 20%
Total number of people = 1000
Number of people who purchased this month = 100
Number of people who did not purchase = 1000 - 100 = 900
therefore,
the number of people who will purchase next month
= 70% of 100 + 20% of 900
= 0.70 × 100 + 0.20 × 900
= 70 + 180
= 250
now,
the number of people who will purchase in 2 month
= 70% of (number of people who will purchase next month) + 20% of (number of people who did not purchase next month)
= 70% of 250 + 20% of (1000 - 250)
= 0.70 × 250 + 0.20 × 750
= 175 + 150
= 325
