Answer:
10x² - 9x
Step-by-step explanation:
(10x² - 10x - 6) + (x + 6)
10x² - 10x - 6 + x + 6
10x² - 9x - 6 + 6
10x² - 9x
Cassie's total spent is equal to money spent on shares bought and commission charges of broker.
<u>Money spent on shares bought:</u>
- 92 shares of Hyren Airlines at $13.70 per share =
- 130 shares of Giaco Household Goods at $3.28 per share =
- 126 shares of Iwad Records at $8.06 per share =
The sum total is 
dollars
<u>Commission charges of broker:</u>
If broker charges $4.25 every 10 shares, he charges 
dollars per share.
Total number of shares bought by Cassie is 
shares.
Total spent on commissions, thus, is 
dollars.
Cassie's total money spent is 
dollars.
Rounded to nearest dollar, it is $2850.
ANSWER: $2850
Answer:
70
Step-by-step explanation:
Answer:
This problem is a great systems of equations problem--you have two different variables: song size and number of songs.
Let's call the number of standard version downloads (S) and the high quality downloads (H).
You can make two statements:
For number of songs downloaded: S + H = 910
For download size: 2.8(S) + 4.4(H) = 3044.
S will be the same number in both equations and H will be the same number in both equations, so to find S, we can rearrange the first statement to H = 910 - S, then substitute or plug in (910 - S) wherever you see an H in the second equation so that you have only S's in your equation. Should look like this:
2.8(S) + 4.4(910 - S) = 3044
2.8S + 4004 - 4.4S = 3044
-1.6S = -960
s = 600
Your question only asks for the standard version downloads, but to help you out in future Systems situations-
You can also solve for H once you have S by plugging it into either of your equations like this:
600 + H = 910
-600
H=310
