Carlos has saved $19.80. Shaq saved 5/6 of the amount that Carlos saved. Deontae saved 4 times as much as Shaq. What is the total saved amount of all three?

Shaq saved 5/6 * $19.80 = $<<5/6*19.80=16.50>>16.50

Deontae saved 4 * $16.50 = $<<4*16.50=66.00>>66.00
So, the total saved amount of all three is $19.80 + $16.50 + $66.00 = $<<19.80+16.50+66.00=102.30>>102.30. Answer: \boxed{102.30}.
