I have no idea

Step-by-step explanation:I'm still in the sixth grade and have not learned this yet

all three statements are true

step-by-step explanation:

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

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
