Jody bought 20 shares of amazon at the close price of $121.00. she bought 20 more shares a year later at the price of $127.00. two years later, she sold all of her shares at the price of $133.00. her broker charges $50 for each transaction. how much money will jody receive after her last transaction?

a. $5430.00
b. $5320.00
c. $5170.00
d. $5280.00

C

Step-by-step explanation:

In total 3 transactions, Jody's broker will take $50*3=$150

Her last transaction will get her ($133 per share for 20+20=40 shares):

But she will get 150 less than 5320 because of broker's charges. She will get:

5320 - 150 = $5170

Answer choice C is right.

78.59 is the mean

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
