For Amounts Between $10,000 and $24,999, a Credit Union Pays

For amounts between $10,000 and $24,999, a credit union pays a rate of 2.5% on term deposits with maturities in the 91 to 120-day range. However, early redemption will result in a rate of 1.75% being applied. How much more interest will a 91-day $20,000 term deposit earn if it is held until maturity than if it is redeemed after 80 days?
