Answer:
Invoice price = $1,180.
Explanation:
interest accrued since last interest payment (interest for 2 months) = Default value * Stated interest * 2 /12
Interest accrued = $1000 * 6% *2/12
Interest accrued = $10
Invoice price = Ask price + interest accrued
Invoice price = $1,170 + $10
Invoice price = $1,180.
