Answer:
12
Step-by-step explanation:
As there are 7 values in the given set, and one is missing, then the full set comprises 8 values.
2,7,8,14,15,20,29.
The middle value is 14 so we need another value, v such that, ½(14 + v) = 13.
This solves as v = 12.
The full set now is,2,7,8,12,14,15,20,29.
S = the number of student tickets sold a = the number of adult tickets sold The drama class sold 25 more student tickets than adult tickets to the fall play s = a + 25 The class collected $660 from ticket sales: 6s + 3a = 660 divide both sides by 3 2s + a = 220 by solving the system of equations s = a + 25 2s + a = 220 we find s = 81.67 student tickets a = 56.67 adult tickets

Answer:
Let C be the cost price of the article. Then:
C(1+30%)=marked price
So:
C(1+30%)=C(1.3)
=1.3C
If the article is then marked down 35%, then its’ price would be:
1.3C(1–35%)=1.3C(.65)
=0.845 or 84.5% of its’ cost
Then:
0.845–1=-0.155
or, a 15.5% loss on the item
