Answer:
[tex]Rp\ 4,552,500[/tex]
Step-by-step explanation:
The question in English is
Heni placed in a bank the amount of Rp. 3,000,000.00. After five months, she had a total of Rp. 3,258,750.00.
How much money will Heni have after 2.5 years?
step 1
Find the rate of interest
we know that
The simple interest formula is equal to
[tex]A=P(1+rt)[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
[tex]t=5/12\ years\\ P=Rp\ 3,000,000\\ A=Rp\ 3,258,750\\r=?[/tex]
substitute in the formula above
[tex]3,258,750=3,000,000(1+r(5/12))[/tex]
[tex]r=[(3,258,750/3,000,000)-1]\(5/12)[/tex]
[tex]r=0.207[/tex]
step 2
For t=2.5 years
[tex]A=3,000,000(1+(2.5)(0.207))[/tex]
[tex]A=Rp\ 4,552,500[/tex]
