can any one do this question?

Sigma Company uses a costing system in which direct materials and direct labour are treated as its only direct costs, and overhead is allocated on the basis of direct labor hours. For 2017, Sigma budgeted 50,000 direct labour hours (at $17 per hour) and $3, 400,000 of overhead. Beta Company operates under the same cost structure, and produces identical products as Sigma. However, Beta uses an activity based costing system to cost its products. Under this system, Beta treats direct materials as the only direct cost. The company identified four activities for which it records all other costs, which are then allocated to products using the following cost drivers: Both Sigma and Beta are preparing bids on two products with the following characteristics: a. Determine Sigma's 2017 overhead rate. b. Determine Beta's 2017 cost allocation rate for each activity. c. Determine Sigma's costs of products A and B. d. Determine Beta's costs of products A and B. e. Describe the advantages/disadvantages of using activity based costing
