You have just been hired by a local plastic pool manufacturer to determine if they are controlling their costs.
You have decided to use your recent knowledge of variance analysis to assist you in this endeavor.
You will analyze the variances as stated in the requirements below.
Required: Make sure you do not forget to label each variance U or F. You need to use cell references for your calculations.
	Variance	U or F
1. Calculate the direct materials price and quantity variance.
Material purchase price variance -Material price variance should be based on material purchased, since you want to isolate the variance as soon as possible.
Material Quantity variance - Material Quantity variance should be based on materials used, since this is monitoring the production efficiency.
2. Calculate the direct labor rate and efficiency variances.
Direct Labor rate variance
Direct Labor Efficiency variance
3. Variable manufacturing overhead spending and efficiency variances.
Variable overhead spending variance
Variable overhead efficiency variance
4. Fixed manufacturing overhead budget variance.
Fixed Manufacturing overhead budget variance
5. Pick out the one most significant variance that you computed above and explain the possible causes of this variance and why you chose it.

Can you explain how to calculate these variances?
