Answer to Question 2
1a. Actual selling price = 79.00
Budgeted selling price = 78.00
Actual sales volume = 7,300 units
Selling price variance = (Actual sales price Budgeted sales price) Actual sales volume
= (79 78) 7,300 = 7,300 Favorable

1c. Price and Efficiency Variances
DMFramesActual ounces used = 4.00 per unit 7,300 units = 29,200 oz.
Price per oz. = 70,080 29,200 = 2.40
DMLensesActual ounces used = 6.00 per unit 7,300 units = 43,800 oz.
Price per oz. = 131,400 43,800 = 3.00
Direct LaborActual labor hours = 145,124 14.20 = 10,220 hours
Labor hours per unit = 10,220 7,300 units = 1.40 hours per unit

2. Possible explanations for the price variances are
(a) unexpected outcomes from purchasing and labor negotiations during the year.
(b) higher quality of frames and/or lower quality of lenses purchased.
(c) standards set incorrectly at the start of the year.
Possible explanations for the uniformly unfavorable efficiency variances are
(a) substantially higher usage of lenses due to poor-quality lenses purchased at lower price.
(b) lesser trained workers hired at lower rates result in higher materials usage (for both frames and lenses), as well as lower levels of labor efficiency.
(c) standards set incorrectly at the start of the year.
