Question

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

Answer 2

t-shirts!!
first tell would you buy this one http://prntscr.com/853gab ?? :P :Plol

Answer 3

lololol

Answer 4

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

Answer 6

70%

Answer 7

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

Answer 8

it's 0.7

Answer 9

now add the number of shirt arrived in shipments

Answer 10

do you know the original equation of recursive function ?

Answer 11
