Answer: f(n) = 0.9 × f(n − 1) + 10, f(0) = 175, n > 0
Step-by-step explanation:
Given: A store had 175 cell phones in the month of January.
Every month, 10% of the cell phones were sold and 10 new cell phones were stocked in the store.
Let n be the number of months
Then when n=0
f(0)=175
After first month , n=1
The number of cell phone in store=
Thus 
Similarly we can do till n months, we get
f(n)=0.9×f(n−1)+10, f(0) = 175, n > 0
