Please help me with this question, thank you!!!

Drilling Company uses activity-based costing and provides this information: Driver Manufacturing Activity Cost Driver Rate Materials handling Number of parts $ 0.5 Machinery Number of machine hours 60 Assembly Number of parts 3.30 Inspection Number of finished units 39 Drilling has just completed 89 units of a component for a customer. Each unit required 109 parts and 3.45 machine hours. The prime cost is $1,390 per finished unit. All other manufacturing costs are classified as manufacturing overhead. Required: 1. Compute the total manufacturing costs and the unit costs of the 89 units just completed using ABC costing. 2. In addition to the manufacturing costs, the firm has determined that the total cost of upstream activities, including research and development and product design, is $189 per unit. The total cost of downstream activities, such as distribution, marketing, and customer service, is $309 per unit. Compute the full product cost per unit, including upstream, manufacturing, and downstream activities. Also compute the relative proportion of each main cost category.Required 1 Required 2 Compute the total manufacturing costs and the unit costs of the 89 units just completed using ABC costing.
