Chandran decides to go into business. he opens a cafe & makes a profit of RM100 in the 1st month.?

Question

for the first year, his profit in each subsequent month is 50% more than that of previous month. in the second year, the profit made by him is reduced by 10% for each subsequent month. help me with the second year.... i have to times by 40% or just minus the 10%??

Answer 1

Profit at the end of first year:
100 * 1.5^11 (for the 11 more months in 1st year, it increases by 50%)
for the next month, take that number, multiply times 0.9 (it's 10% less).
Second year has 12 months, so if you want the profit at the last month of second year,

100 * 1.5^11 * 0.9^12

Answer 2

Multiply by 1.5 for the first year. Divide by 1.1 for the second year. You are using the previous month's profit as a baseline so the 50% per month increase from the first year is irrelevant. But you shouldn't be multiplying for the second year since there is a decrease in profits starting with the second year.

Answer 3

The second year values will be
100(1.5^11)(0.9^n)
