Extracted text: A quantity of steel in the amount of $423,000.0 is needed for a project, payment due (from contractor to steel fabricator) at the project begin date. The steel is expected to be erected in Month 2 and Month 3, with billing at the end of these months and subsequent payment from the owner (to the contractor) at the end of Month 3 and Month 4. Assume half the the payment occurs at the end of Month 3 and the other half at the end of Month 4. Using an annual interest rate of 18%, which is a monthly interest rate of 1.5%, to finance the purchase with a short-term line of credit loan, determine the total interest accumulated for this steel purchase until payment is received (from the owner).
