Let's say the amount they both had in March is x.
In April, Isaiah's account increased to x + $210.
Freddie increased his account with 15/100*x = x/20.
The total amount Freddie had in his account in April is x + x/20 = 21x/20
To compare their balances, we equate the amounts: x + $210 = 21x/20
Multiplying both sides by 20: 20x + $4200 = 21x
Subtracting 20x on both sides: $4200 = x. Answer: \boxed{4200}.
