Q = The Ammount Of Cranberry Juice
(q+4)*4.50=q*6.30+4*3.60
4.5*q+18=6.30*q+14.4
6.30*q-4.5*q=18-14.4
1.8*q=3.6
q=3.6/1.8
It Would Be 2 Quarts Of Cranberry Juice

Step-by-step explanation:
30,26,22,18,14,10,8,4,-2.
John's effective annual rate is about
(1 +.0576/4)^4 -1 ≈ 5.8856%
According to the "rule of 72", John's money will have doubled in
72/5.8856 = 12.23 years
John's balance will be $4500 in 1989.
