Jupiter Software Inc. is planning to issue two types of 25-year, bonds to raise a total of $6 million, $3 million from each type of bond.

First, 3,000 bonds with an 11% semiannual coupon will be sold at their $1,000 par value to raise $3,000,000. These are called par bonds.

Second, Original Issue Discount (OID) bonds, also with a 25-year maturity and a $1,000 par value, will be sold, but these bonds will have a coupon rate of only 6.50%, paid semiannually. The OID bonds must be offered at below par in order to provide investors with the same effective yield as the par bonds.

How many OID bonds must the firm issue to raise $3,000,000? (Tip: Disregard flotation costs, and round your final answer up to a whole number of bonds.)
