Identify the following efficiency and effectiveness variances: a) 'Ihtal sales variance for funds received; Total Sales Variance = $2 Favorable [$1+$1] Note: Given rounding, this is close to zero price variance as price remains constant at $4,993 as dictated by government efficiency price determination. It is important to remind students that the volume measure (WACU) is not representative of the number of patients but the equivalent weight (see case specifics that explains 1 hip patient is equivalent to 4.1742 WACUs x $4,993; 1 knee patient is equivalent to 1.1000 WACUs x $4,993). b) 'Ihtal variable cost variance; Total Variable Cost Variance = $323 Favorable [-$573 + $685 + $37 + $174] c) Thu] xed cost variance; The fixed cost variance is $1,654 Unfavorable [-$579 + -$1,075] This unfavorable variance represents over-spending. Both \"Hospital 8: Administration\" and \"Other\" fixed costs categories increased. Note xed costs do not vary with patient volumes, hence, they are not \"exed\" with actual output volumes in the flexible budget and only examined for increases or decreases in expenditure between budget and actual
