The correct answer is B.

Explanation:

Giving the following information:

James Inc.'s flexible budget for June, based upon actual output, called for the use of 10,500 pounds of materials at a standard cost of $7.40 per pound. The Production Department used 10,700 pounds of materials costing $7.10 per pound during June.

To calculate the direct materials price variance, we need to use the following formula:

Direct material price variance= (standard price - actual price)*actual quantity

Direct material price variance= (7.4 - 7.10)*10,700= $3,210 favorable

In the area that she observed, the water level fell 13.64mm over 6.4 years, for an average annual rate of change of:
-13.64 ÷ 6.2 = -2.2 mm/ year. 

The difference between how much average water levels rose and how much water levels in her part of the river fell is:
1.8 -(-2.2) = 4 mm/year

During the 6.2 year period: 
4 mm/year * 6.2 = 24.8 mm
