Cost of Trade Credit

Grunewald Industries sells on terms of 1/10, net 50. Gross sales last year were $4,072,000, and accounts receivable averaged $442,000.

(Hint: Calculate sales/day based on a 365-day year; then get average receivables of discount customers; then find the DSO for the nondiscount customers.)
