The total of both variances equals the total direct materials variance. To apply this method to the Band Book example, take a look at the next diagram. Start at the bottom. Direct materials actually cost $297,000, even though the standard cost of the direct materials is only $289,800.
These factors can all reduce the space around a nerve root in the lower back, interfering with nerve function. Symptoms of sciatica may include pain, weakness, numbness or tingling in the low back, buttocks, posterior thighs, legs and feet. Symptoms often occur only on one side of the body.
