can you explain these problems with solutions? thank you :)

Lane Company manufactures a single product requiring a great deal of hand labor. Overhead cost is applied based on standard direct labor-hours. The budgeted variable manufacturing overhead is $3.60 per direct labor-hour and the budgeted fixed manufacturing overhead is $1,140,000 per year. The standard quantity of materials is 4 pounds per unit and the standard cost is $7.00 per pound. The standard direct labor-hours per unit is 1.5 hours and the standard labor rate is $12.80 per hour. The company planned to operate at a denominator activity level of 150,000 direct labor-hours and to produce 100,000 units during the most recent year. Actual activity and costs for the year were as follows: Required: 1. Compute the predetermined overhead rate for the year. Break the rate down into variable and fixed elements. 2. Prepare a standard cost card for the company's product. 3a. Compute the standard direct labor-hours aliowed for the year's production. 3b. Complete the following Manufacturing Overhead T-account for the year. 4. Determine the reason for any underapplied or overapplied overhead for the year by computing the variable overhead rate and efficlency variances and the fixed overhead budget and volume variances. Complete this question by entering your answers in the tabs below. Determine the reason for any underapplied or overapplied overhead for the year by computing the variable overhead rate and efficiency variances and the fixed overhead budget and volume variances. Note: Indicate the effect of each variance by selecting " F " for favorable, " U " for unfavorable, and "None" for no effect (lie., zero variance). Input all amounts as positive values.
