Sara blake's grandmother gave her $3000.00 to save for college. she put it in a savings account that earns 6% interest per year. the money was in the account for 8 years. how much simple interest did she earn?

•P is the principal amount, $3000.00.

•r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.

•t is the time involved, 8 years time periods.

•So, t is 8 year time periods.

To find the simple interest, we multiply 3000 × 0.06 × 8 to get that:

The interest is: $1440.00

1440

Step-by-step explanation:

to get the interest you have to multiply the principal and rate and time (P x R x T)

I = 3000 x 0.06 x 8     (remember 6% turns into a decimal 0.06)

I = 1140
