Answer:

D. Subtract the sum of the three test scores from the product of 75 and 5, and divide the result by 2

Step-by-step explanation:

Alright imma try and make this as simple as possible.

My steps:

1) follow the answers steps:

(100 + 85 + 70) - (75 • 5) = -120

-120 divided by 2 = -60

Now, yes the answer is negative but check this out!

3) add 60 twice to 100, 85, and 70: ( 100 + 85 + 70 + 60 + 60) = 375

4) then divide 375 by 5: 375 divided by 5 = 75

Which is our mean! And there you have it! I really hoped this helped and your not confused. Good luck! :)
