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
give each letter a number: A=1, B=2, C=3, D=4
ADD = 1+4+4=9
BAD = 2+1+4 = 7
CAD = 3+1+4 = 8
So ADA = 1+4+1 = 6
