Answer:
Total expending 21,320
Explanation:
Assuming the administrative expense are also paid on cash during the period
1,300 units x $4.20 = 5,460 Variable expending
19,240 fixed cost - 3,380 depreciation (non-monetary) = 15,860 Fixed expending
Total expending 5,460 + 15,860 = 21,320
Remember:
Depreciation and amortization are non-monetary term, they don't involve a cash disbursement.
