## anonymous one year ago 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? f(n) = f(n - 1) • 0.3 + 25, n > 0 f(n) = 100 - f(n - 1) • 0.3 + 25, n > 0 f(n) = f(n - 1) • 0.7 + 25, n > 0 f(n) = 100 - f(n - 1) • 0.7 + 25, n > 0

i was kidding lol okay so if 30% were sold how many percents you have now ? subtract from 100%

6. anonymous

70%

7. Nnesha

yes right now divide that by 100 change percent to decimal $\frac{ 70 }{ 100 }$

8. anonymous

it's 0.7

9. Nnesha

now add the number of shirt arrived in shipments

10. Nnesha

do you know the original equation of recursive function ?
