NEED HELP!!!!! You sell 400 shares of AVG Technologies (AVG). You purchased the stock at $12.77 per share and sold it at $13.33
Mandarinka [93]

Answer:

$224

Step-by-step explanation:

You purchased the stock at $12.77 per share, so the total amount you purchase for is:

400 shares * $12.77 = $5108

You spent $5108 on the stock shares.

You sold the stock at $13.33 per share, so the total amount you sold for is

400 shares * $13.33 = $5332

You got $5332 by selling the stock shares.

Profit = $5332 - $5108 = $224

Answer:

He can buy up to 20 tickets (ie 20 tickets or less)

The equation is 10+3.25x+5 = 80

========================================================

Explanation:

10 = admission cost

3.25 = cost per ticket

x = number of tickets

3.25x = cost from buying x number of tickets

5 = cost of nachos & coke

10+3.25x+5 = total cost of admission, tickets, and food/drink

10+3.25x+5 = 80 since this is the amount he has in his pocket

---------------

Let's solve for x

10+3.25x+5 = 80

3.25x+15 = 80

3.25x = 80-15 .... subtract 15 from both sides

3.25x = 65

x = 65/3.25 ........ divide both sides by 3.25

x = 20

Billy can buy up to 20 tickets (ie 20 tickets or less).
