Answer:
Step-by-step explanation:
Let J and M represent the current ages of Jacob and his Mother.
<u>currently</u>:
M = 3 +9J
<u>in 11 years</u>:
M+11 = 5 +3(J+11)
Using the first equation to substitute for M in the second, we have ...
(3 +9J) +11 = 5 +3(J +11) . . . . . substitute for M
9J +14 = 3J +38 . . . . . . simplify
6J + 24 . . . . . . . . . . subtract 3J+14
J = 4 . . . . . . . . . . divide by 6
M = 3 +9(4) = 39
Jacob is 4 and his mother is 39.

Answer:
It will be worth $1732.30.
Step-by-step explanation:
After 1 year : 6000 x .78 = 4680
2 yr - 4680 x .78 = 3650.4
3 yr - 3650.4 x .78 = 2847.312
4 yr - 2847.312 x .78 = 2220.90336
5 yr - 2220.90336 x .78 = 1732.304621
1732.30
