Detailed Answer
Answer (B) is correct. Projected credit sales for the year under the old credit policy were $37,500,000 ($50,000,000 × 75%), resulting in an average balance in receivables of $2,083,333 [$37,500,000 × (20 days ÷ 360 days)]. Under the new policy, credit sales will be $46,875,000 ($37,500,000 × 1.25), resulting in an average receivables balance of $3,906,250 [$46,875,000 × (30 days ÷ 360 days)]. Hence, the expected increase in the balance is $1,822,917 ($3,906,250 – $2,083,333 .
