Answer:
7
232
Step-by-step explanation:
First
Normally the average of something is total something over total time. I'll do it that way and see what happens.
The total time is ( 4 - 2) = 2 hours.
f(x) = 2^4 - 2 = 14
Change = 14/2 = 7 per hour.
Second
Average = Increase / time.
10000 (1.02)^10 - 10000 * (1.02)^5
10000*1.22 - 10000*1.104
12,200 - 11040
1160
The average per year = 1160 / 5 = 232
8 = 2 x 2 x 2
11 = 11
12 = 2 x 2 x 3
LCM = 2 x 2 x 2 x 3 x 11 = 264
A*25+b*35=10250
a +b = 350 | * -25
25a + 35b= 10. 250
-25a -25 b= -8.750
------------------------------
10b = 1500
b=1500:10
b=150 tickets cost 35 $
a= 350-150
a= 200 tickets cost 25 $
