Answer is D
Since the bank gave them a credit to withdraw money to pay for the play. And the play was 3,200.00. The credit is on -3,200.00.
Since each ticket is $10.00 and 1,007 ppl attended. You multiply them together
1,007 x 10 = 10,070.
Since you depositing it to the credit card the -3,200.00 will ver deducted from the 10,070.00 that you put in. So you subtract.
$10,070.00 - $3,200.00 = $6,870.00.
