I really need this answer and the steps

Koenan makes handhold calculators in two models- basic and professional, Keenan estimated $1,149,500 of manufacturing overhead and 605,000 machine hours for the year. The basic model actually consumed 280,000 machine hours, and the professional model consumed 325,000 machine hours. The predefermined overhead allocation rate using machine hours as the allocation base is $1,90 per machine hour, with the allocated overhead costs splt between the basic model and the professional model by $532,000 and $617,500, respectively. [Click the icon to view the data using multiple department allocation rates.) (Click the icon to view additonal data.) Requirement 1. Keenon expects to produce 175,000 basic models and 175,000 professional models, Compute the predetermined overhead allocation rates using activity-based costing. How much overhead is allocated to the basic model? To the professional model? Round the materials handling allocation rate to four decimal places and the remaining allocation rates to the nearest cent. Begin by selecting the formula to calculate the predetermined ovechead (OH) allocation rate. Then enter the amounts to compute the allocation rate for each activity. (Abbroviation used: Qty = quantity. Enter the materials handling allocation rate to four decimal places, and the remaining allocation rates to the nearest cent.) Print Done 1. Keenan expects to produce 175,000 basic models and 175,000 professional models. Compute the predetermined overhead allocation rates using activity-based costing. How much overhead is allocated to the basic model? To the professional model? Round the materials handling allocation rate to four decimal places and the remaining allocation rates to the nearest cent. 2. Compare the activity-based costing results from Requirement 1 with the company's results using a single plantwide rate and using multiple department rates by summarizing the total and per unit overhead allocated to each model under each of the three different allocation methods. Round per unit amounts to the nearest cent. What conclusions can you draw
