Greetings! I could use some help with this longer Managerial Accounting exercise, a detailed step-by-step would help me best!!

Comprehensive flexible budgets and variance analysis; Lexi Belcher picked up the monthly report that Irvin Santamaria left on her desk. She smiled as her eyes went straight to the bottom line of the report and saw the favorable variance for operating income, confirming her decision to push the workers to get those last 300 cases off the production line before the end of the month.
But as she glanced over the rest of 'da numbers, Lexi couldn't help but wonder if there were errors in some of the line items. She was puzzled at how most of the operating expenses could be higher than the budget since she had worked hard to manage the production line to improve efficiency and reduce costs. Yet the report, shown below, showed a different story.
	Actual	Budget	Variance
Cases produced and sold	10,300	10,000	300 F
Sales revenue	$ 2,080,600.00	$ 2,000,000.00	$80,600 F
Less variable expenses	$ -	$ -	$ -
Direct material	$ 593,160.00	$ 575,000.00	$18,160 U
Direct labor	$ 290,310.00	$ 280,000.00	$10,310 U
Variable manufacturing overhead	$ 231,450.00	$ 225,000.00	$6,450 U
Variable selling expenses	$ 112,340.00	$ 110,000.00	$2,340 U
Variable administrative expenses	$ 43,285.00	$ 42,000.00	$1,285 U
Total variable expenses	$ 1,270,545.00	$ 1,232,000.00	$38,545 U
Contribution margin	$ 810,055.00	$ 768,000.00	$42,055 F
Less fixed expenses	$ -	$ -	$ -
Fixed manufacturing overhead	$ 122,000.00	$ 125,000.00	$3,000 F
Fixed selling expenses	$ 86,280.00	$ 85,000.00	$1,280 U
Fixed administrative expenses	$ 149,000.00	$ 148,000.00	$1,000 U
Total fixed expenses	$ 357,280.00	$ 358,000.00	($720) F
Operating income	$ 452,775.00	$ 410,000.00	$42,775 F
Lexi picked up the phone and called Irvin. "Irvin, I don't get it. We beat the budgeted operating income for the month, but look at all the unfavorable variances on the operating costs. Can you help me understand what's going on?" "Let me look into it and I'll get back to you," Irvin replied.
Irvin gathered the following additional information about the month's performance.
* Direct materials purchased: 55,000 pounds at a total of $632,500
* Direct materials used: 51,200 pounds
* Direct labor hours worked: 26,500 at a total cost of $290,310
* Machine hours used: 52,200
Irvin also found the standard cost card for a case of product.
	Standard Price	Standard Quantity	Standard Cost
Direct materials	$11.50 per pound	5 pounds	$57.50
Direct labor	$11.20 per DLH	2.5 DLH	$28.00
Variable overhead	$4.50 per MH	5 MH	$22.50
Fixed overhead	$2.50 per MH	5 MH	$12.50
Total standard cost per case			$120.50
I need assistance with the following portions, thank you VERY MUCH!!! A: Calculate the direct materials price variance for the month. B: Calculate the direct materials quantity variance for the month. C: Calculate the direct labor rate variance for the month. D: Calculate the direct labor efficiency variance for the month. E: Calculate the variable overhead spending variance for the month. F: Calculate the variable overhead efficiency variance for the month. G: Calculate the fixed overhead spending variance for the month. H: Prepare performance report that will assist Lexi in evaluating her efforts to control production costs. I: Based on your review of the performance report you prepared; do you think Lexi did a good job of controlling production expenses during the month? Why or why not?
