B. f(n) = 0.2 x f(n - 1) , f(0) = 1500 , n > 0
C. f(n) = 0.8 x f(n - 1) , f(0) = 1500 , n > 0
D. f(n) = 1500 - 0.2 x f(n - 1) , f(0) =1500 , n > 0

the answers c

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
