13. Picture is cut off. Insufficient information is shown.
14. ST = 2×(XY)
8z +3 = 2(3z +2)
2z = 1
z = 1/2
Based on the quantity sold and the price, the profit per unit is <u>$5</u> and the total profit is<u> $2,500</u>
The profit made from each unit sold can be found as:
<em>= Market price - Average cost </em>
= 14 - 9
= $5
The total profit would therefore be:
<em>= Profit per unit x Number of units sold </em>
= 5 x 500
= $2,500
In conclusion, the profit per unit is $5 and the total profit is $2,500

Answer:
Step-by-step explanation:
As the numbers are only between 1 and 30
Total number of possible combinations = 30×30×30 = 27000
If there are 100 attempts then
∴ Probability someone can guess the correct combination given 100 attempts is 
Y= -7/15
Hope this is good enough :D
