x is the number od doubling periods ( which is given as every 7 years)
28 years / 7 = 4 doubling periods in 28 years
so x = 4
so you now have:
f(x) = 8000 * 2^4
2^4 = 16
so 8000 * 16 = $128,000 would be the answer

Answer: question 6
4/7*8/10 =
first multiply the numeratores the the denominatos.
4*8=32 so this will be numerator.
7*10=70 this is denominator.
so answer is 32/70
same way question 7 is 28/40
question 8
11/2 *9/4 = 99/8= 12 3/8
question 9
convert to improper
9/5*7/3= 63/15 4 3/15
question 10
21/8*16/7= 336/56= 6/6
