Question

CodeHead Software Inc. does software development. One important activity in software development is writing software code. The manager of the WordPro Development Team determined that the average software programmer could write 25 lines of code in an hour. The plan for the first week in May called for 4,650 lines of code to be written on the WordPro product. The WordPro Team has five programmers. Each programmer is hired from an employment firm that requires temporary employees to be hired for a minimum of a 40-hour week. Programmers are paid $32.00 per hour. The manager offered a bonus if the team could generate more lines for the week, without overtime. Due to a project emergency, the programmers wrote more code in the first week of May than planned. The actual amount of code written in the first week of May was 5,650 lines, without overtime. As a result, the bonus caused the average programmer's hourly rate to increase to $40.00 per hour during the first week in May. Enter a favorable variance as a negative number using a minus sign and an unfavorable variance as a positive number. If an amount is zero, enter "0" and choose "Not applicable" from the dropdown.
If the team generated 4,650 lines of code according to the original plan, what would have been the labor time variance?

Answer 1

Answer:

Explanation:

Standard hours per week = 40 hours

Standard rate per hour = $32

Actual rate per hour = $40

Labour rate variance = 40 - 32 = $8 (unfavourable)

Actual cost per week = 40 × 40 = $1600

Standard cost per week = 40 × 32 = $1280

Labour cost variance = actual cost per week - standard cost per week

= 1600 - 1280

= $320 (unfavourable)

Actual codes written in first week = 5650

Standard codes per week = 5 × 25 × 40 = 5000

Actual cost per code = 1600/5660 = $0.2832

Standard cost per code = 1280/5000 = 0.256

Labour efficiency variance = 0.2832 - 0.256 = $0.0272 (unfavourable)

If the team generated 4,650 lines of code according to the original plan:

Code generated = 4650

Number of programmers = 5

Average codes per hour per programmer = 25

Total codes per hour = 25 × 5 = 125

Standard codes per week = 40 × 125 = 5000

Actual time to write 4650 codes = 4650/125 = 37.2 hours

Standard time = 40 hours

Idle time = 40 - 37.2 = 2.8 hours

Labour time variance = 2.8 hours

Cost of idle time = 2.8 × 32 = $89.6 (unfavourable)
