Leon deposited $30000 in a bank which paid 2% interest per year. After 1 year, Leon withdrew all his money including the interest. how much money did Leon withdraw?

The amount of money Leon had after 1 year will be given by:

A=P (1+r) ^n

where:

P=principle

r=rate

n=time

But from the information given:

P=$30,000, r=2%, n=1 year

thus

A=30000 (1+2/100) ^1

A=30000 (1.02) ^1

A=$30600

Thus amount after 1 year was $30600
