Answer:
B) $50,000
Explanation:
Month total sales $ collected outstanding credit
January $40,000 $16,000 $24,000
February $60,000 $24,000 + $12,000 $12,000 + $36,000
March $50,000 $20,000 + $12,000 + $18,000 $18,000 + $30,000
during March, Eccleston should collect ($50,000 x 40% from current sales) + ($24,000 x 50% from January) + ($36,000 x 50% from February) = $20,000 + $12,000 + $18,000 = $50,000
