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 s
tocked in the store.
Which recursive function best represents the number of cell phones in the store f(n) after n months?
f(n) = 175 − 0.9 × f(n − 1) + 10, f(0) = 175, n > 0
f(n) = 0.1 × f(n − 1) + 10, f(0) = 175, n > 0
f(n) = 175 + 0.9 × f(n − 1) + 10, f(0) = 175, n > 0
f(n) = 0.9 × f(n − 1) + 10, f(0) = 175, n > 0
1 answer:
F(n) = 175 + 0.9 × f(n − 1) + 10, f(0) = 175, n > 0
