Graham Petroleum produces oil. On May 1, it had no work-in-process inventory. It started production of 244 million barrels of oi
lisov135 [29]

Answer:

Explanation:

Number of completed barrels = 216 + (244-216)*60%

= 233 barrels

Cost per barrel = (3245+3230)/233 = 27.8

Cost of oil shipped in pipeline = 216 * 27.8= 6003 millions

Cost of work in process ending inventory = (244-216)*60% * 27.8

= 467.04 million

Serjik [45]

Answer:

a. -$783 Unfavorable

b. 550 Favorable

Explanation:

a. The computation of Variable Overhead Rate Variance is shown below:-

Variable Overhead Rate Variance = Actual hours × (Standard Variable Overhead rate per hour - Actual Variable Overhead rate per hour)

= 8,700 × ($4.10 - ($36,540 ÷ 8,700)

=  8,700 × ($4.10 - $4.19)

= 8,700 × -$0.09

= -$783 Unfavorable

b. The computation of Variable Overhead Efficiency Variance is shown below:-

Variable Overhead Efficiency Variance = Standard Variable Overhead Rate per Hour ×  (Standard Hours for Actual Production - Actual Hours)

= 5.5 × ((5.5 × 1,600) - 8,700)

= 5.5 × (8,800 - 8,700)

= 5.5 × 100

= 550 Favorable
