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
is it C ? I will give fan and medals

Best ResponseYou've already chosen the best response.0f(n) = 0.8 × f(n  1) + 10, f(0) = 150, n > 0 because if n=1 f(1)=0.8xf(11)+10 f(1)0.8x150+10 0.8x150 representes the 20% sell +10 represent the new laptop
