A store had 100 t-shirts. Each month, 30% of the t-shirts were sold and 25 new t-shirts arrived in shipments. Which recursive function best represents the number of t-shirts in the store, given that f(0) = 100? (1 point) Question options:

1)

f(n) = f(n − 1) ⋅ 0.3 + 25, n > 0

2)

f(n) = 100 − f(n − 1) ⋅ 0.3 + 25, n > 0

3)

f(n) = f(n − 1) ⋅ 0.7 + 25, n > 0

4)

f(n) = 100 − f(n − 1) ⋅ 0.7 + 25, n > 0
