Macmillan Learning This activity is a companion to the in-text Investigating Life box "Can Chlorella Algae Be Grown in Municipal Sewage Wastewater for Biofuel Production?" Be sure to review that box before proceeding. In the Investigating Life box, we saw that Chlorella minutissima algae can be grown effectively in municipal wastewater. Bhatnagar et al. also explored whether amount of light exposure affects growth of Chlorella minutissima by measuring generation time in response to light intensity. As generation time increases in Chlorella minutissima algae, what can we predict happens to growth rate? It's impossible to tell It stays the same It increases It decreases

Antuan Company set the following standard costs per unit for its product. Direct materials (3.0 pounds @ $4.00 per pound) $ 12.00 Direct labor (1.9 hours @ $13.00 per hour) 24.70 Overhead (1.9 hours @ $18.50 per hour) 35.15 Standard cost per unit $ 71.85 The standard overhead rate ($18.50 per direct labor hour) is based on a predicted activity level of 75% of the factory's capacity of 20,000 units per month. Following are the company's budgeted overhead costs per month at the 75% capacity level. Overhead Budget (75% Capacity) Variable overhead costs. Indirect materials $ 15,000 Indirect labor 75,000 Power 15,000 Maintenance 30,000 Total variable overhead costs 135,000 Fixed overhead costs Depreciation-Building 25,000 Depreciation-Machinery 18,000 Taxes and insurance 280,250 Supervisory salaries 280,250 Total fixed overhead costs 392,250 Total overhead costs 527,250 The company incurred the following actual costs when it operated at 75% of capacity in October. Direct materials (46,000 pounds @ $4.20 per pound) $ 193,200 Direct labor (21,000 hours @ $13.10 per hour) 275,100 Overhead costs Indirect materials $ 41,550 Indirect labor 17,250 Power 34,850 Maintenance 16,280 Depreciation-Building 25,000 Depreciation-Machinery 18,000 Taxes and insurance 280,250 Supervisory salaries 280,250 Total costs $ 1,153,850 Required: 1.
