Calculate the simple interest earned on a deposit of $3,000 at 6% for 5 years.

The simple interest formula is

i = p*r*t

where,

i = simple interest earned

p = principal (amount deposited)

r = interest rate in decimal form

t = time in years

In this case,

i = unknown for now

p = 3000

r = 0.06 (since 6% = 6/100 = 0.06)

t = 5

Let's plug in those three given values to get

i = p*r*t

i = 3000*0.06*5

i = 900

Final Answer: 900 dollars
