J = Julie
B = Bryan
O = Joe
K = Kent
(J + B + O + K) / 4 = 63
J = .25O
B = O + 10
K = O - 18
Substitute:
((.25O) + (O + 10) + O + (O - 18)) / 4 = 63
(3.25O - 8) / 4 = 63
3.25O - 8 = 252
3.25O = 260
O = 80
K = O - 18
K = 80 - 18
K = 62
B = O + 10
B = 80 + 10
B = 90
Therefore,
B + K = 152

Explanation:
If we set
x
to be the amount of money she deposited initially, then we get an equation:
x
⋅
1.06
12
=
5000
1.06 because her money is multiplied by 106% every time, and to the power of 12 because interest is compounded 3 times per year for 4 years.
So just solve for
x
:
