Question

i need help i need to find the balance in each compound interest account:
$1400 after 3 years at 5.5%
i got:
B= P (1 + r) t
=1400 (1 + .055)3

I am stuck and don't know how to do this

#2 $1800 after 11 years @ 6.0%


#3 $900 after 10 years @ 4.62%

#4 $2500 after 50 years @ 2.2%

Answer 1

B= P (1 + r)^t
The t is an exponent.

1400 (1 + .055)^3 = $1643.94

This assumes annual compounding. Most accounts compound more frequently
