the stock for p dollars and paid a flat fee of $22. Which expression below models
Tyanna's net proceeds algebraically?
A.
B.
C.
D.
p - x(1.04d - 22)
p - 1.04(xd – 22)
p - (1.04xd + 22)
(1.04xd +22) - p

p - (1.04xd + 22)

Step-by-step explanation:

Tyanna bought x number of shares for d dollars ⇒ xd

paid a 4% commission ⇒ 0.04 xd

Tyanna paid = xd + 0.04xd = 1.04 xd

She sold the stock for p dollars  ⇒ p

paid a flat fee of $22

The sell price = p - 22

Net = p - 22 - 1.04xd = p - (22 + 1.04 xd)

The answer is option ⇒ p - (1.04xd + 22)

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
