If 30% of the t-shirts are sold, then f(n) includes f(n-1)*0.7. If we add 25 new t-shirts, the total value of f(n) is f(n-1)*0.7+25. C is the correct answer.
Answer:
recursive function best represents the number of t-shirts in the store, given that f(0) = 100 is:
f(n) = f(n - 1)×0.7 + 25,n > 0.
Step-by-step explanation:
A store had 100 t-shirts i.e. f(0) = 100.
Each month, 30% of the t-shirts were sold this means that each month the t-shirts left are 70% i.e. 0.7 of the total shirts in that month.
Also 25 new t-shirts arrived in shipments.
This means that at the end of month the t-shirts in the store will be 0.7 times the t-shirts in start of that month plus 25.
Hence, the expression that best represents this problem is given by:
f(n) = f(n - 1)×0.7 + 25,n > 0.
Where n represents the month.
