Problem 11–10 (continued)
Note that all of the price variance is due to the hospital’s 4% quantity
discount. Also note that the $8,000 quantity variance for the month is
equal to nearly 30% of the standard cost allowed for plates. This
variance may be the result of using too many assistants in the lab.
Problem 11–10 (continued)
2. b. The policy probably should not be continued. Although the hospital is
saving $1.75 per hour by employing more assistants relative to the
number of senior technicians than other hospitals, this savings is
more than offset by other factors. Too much time is being taken in

Alternatively, the variances can be computed using the formulas:
Variable overhead efficiency variance = SR (AH – SH)
= $6 per hour (1,800 hours – 1,350 hours)
Yes, the two variances are related. Both are computed by comparing
Problem 11–13 (45 minutes)
1. a. Materials price variance = AQ (AP – SP)
6,000 pounds ($2.75 per pound* – SP) = $1,500 F**
$16,500 – 6,000 pounds × SP = $1,500***
6,000 pounds × SP = $18,000
