Answer 1

Question 28

A store had 150 laptops in the month of January. Every month, 20% of the laptops were sold and 10 new laptops were stocked in the store.

Which recursive function best represents the number of laptops in the store f(n) after n months?

f(n) = 150 - 0.8 × f(n - 1) + 10, f(0) = 150, n > 0

f(n) = 0.2 × f(n - 1) + 10, f(0) = 150, n > 0

f(n) = 0.8 × f(n - 1) + 10, f(0) = 150, n > 0

f(n) = 150 + 0.8 × f(n - 1) + 10, f(0) = 150, n > 0

Nope, wait.
