Answer:what is unknown:Ariel's original deposit amount

Formula:A=P(1+r/n.t)³⁰

Given:A=(pesos sign) 550,450.00

T=30years

r=8.5%(convert to decimal 8.5÷100=0.085

Solution:550,450=P(1+8.5%)³⁰

550,450=P(1+8.5/100)³⁰

550,450=P(1+0.085)³⁰

550,450=P(1.085)³⁰

P=550,450/(1.085)³⁰

P=47623.98

Ariel's original deposit amount is (pesos sign) 47,623.98 or (pesos sign) 47,624
