I was wondering if someone can help me with the following question? Thanks very much

An investor has to to pay an investment project that is worth 6,200,000 dollars and plans to sell many zero-coupon bonds to cover the cost.

Each of this bond has a face value of $1,000, a maturity of 20 years and a yield of 9.5%.

At minimum, how many of these bonds have to be sold by the investor?
