Hello, I am having a hard time figuring out the correct answer to this problem:

Delaware Corp. prepared a master budget that included $21,360 for direct materials, $33,600 for direct labor, $18,000 for variable overhead, and $46,440 for fixed overhead. Delaware Corp. planned to sell 4,000 units during the period, but actually sold 4,300 units. What would Delaware's total costs be if it used a flexible budget for the period based on actual sales?

The answer I am coming up with is not none of the selections and I know I am missing a step. Any assistance would be appreciated. Thanks.
