Answer:
$620,000
Explanation:
the total cash received (dirty price) = clean price + accrued interest = (1.02 x $600,000) + ($600,000 x 8% x 2/12) = $612,000 + $8,000 = $620,000
the clean price of a bond refers to the price of the bond without any type of accrued interest, i.e. the price that the issuer would receive if it sold them at the same date that they were issued.
The dirty price includes both the clean price plus any accrued interest
