A business had opening debtors of 6,000, closing debtors of 4,500, cash received from debtors of 18,000, and bad debts written off of 500, What was the total credit sales?

• Opening Debtors: \6,000$
• Closing Debtors: \4,500$
• Cash received from Debtors: \18,000$
• Bad Debts Written Off: \500$
• Total Credit Sales: Let this be $X$

The basic formula for a Debtors Control Account is:

$\$6,000 + X = \$18,000 + \$500 + \$4,500$

First, sum the right side of the equation: $\$6,000 + X = \$23,000$ Now, subtract the opening debtors from both sides: $X = \$23,000 - \$6,000$ $X = \$17,000$

The total credit sales are $17,000.

Comparing this to the options:
A. $16,000 B.$20,000 C. $19,000 D.$17,000

The correct option is D.

The final answer is \boxed{\text{D. \17,000}}$.
