Cornerstone Exercise 9.1 (Algorithmic) Calculating Standard Quantities for Actual Production

Guillermo's Oil and Lube Company is a service company that offers oil changes and lubrication for automobiles and light trucks. On average, Guillermo has found that a typical oil change takes 30 minutes and 6.8 quarts of oil are used. In June, Guillermo's Oil and Lube had 940 oil changes.

Required:

1.Calculate the number of quarts of oil that should have been used (SQ) for 940 oil changes. _________________ quarts

2.Calculate the hours of direct labor that should have been used (SH) for 940 oil changes. _________________ direct labor hours

3.What ifthere had been 930 oil changes in June? Would the standard quantities of oil (in quarts) and of direct labor hours be higher or lower than the amounts calculated in Requirements 1 and 2? _________________

What would the new standard quantities be? Round your answers to two decimal places.

SQ	_________________	quarts
SH	_________________	direct labor hours

Cornerstone Exercise 9.2 (Algorithmic) Calculating the Direct Materials Price Variance and the Direct Materials Usage Variance

Guillermo's Oil and Lube Company is a service company that offers oil changes and lubrication for automobiles and light trucks. On average, Guillermo has found that a typical oil change takes 29 minutes and 6.2 quarts of oil are used. In June, Guillermo's Oil and Lube had 900 oil changes.

Guillermo's Oil and Lube Company provided the following information for the production of oil changes during the month of June:

Actual number of oil changes performed: 900 Actual number of quarts of oil used: 5,400 quarts Actual price paid per quart of oil: $5.10 Standard price per quart of oil: $5.05

Required:

1.Calculate the direct materials price variance (MPV) and the direct materials usage variance (MUV) for June using the formula approach. If required, round your answers to the nearest cent.

MPV	$ _________________	_________________
MUV	$ _________________	_________________

2.Calculate the total direct materials variance for oil for June. If required, round your answer to the nearest cent.

$ _________________ _________________

3.What ifthe actual number of quarts of oil purchased in June had been 5,330 quarts, and the materials price variance was calculated at the time of purchase? If required, round your answers to the nearest cent.

What would be the materials price variance (MPV)?

Cornerstone Exercise 9.3 Calculating the Direct Labor Rate Variance and the Direct Labor Efficiency Variance

Guillermo's Oil and Lube Company is a service company that offers oil changes and lubrication for automobiles and light trucks. On average, Guillermo has found that a typical oil change takes 24 minutes and 6.2 quarts of oil are used. In June, Guillermo's Oil and Lube had 980 oil changes.

Guillermo's Oil and Lube Company provided the following information for the production of oil changes during the month of June:

Required:

1.Calculate the direct labor rate variance (LRV) and the direct labor efficiency variance (LEV) for June using the formula approach.

LRV	$ _________________	_________________
LEV	$ _________________	_________________

2.Calculate the total direct labor variance for oil changes for June. $ _________________ _________________

3.What if the actual wage rate paid in June was $12.40? What impact would that have had on the direct labor rate variance (LRV)? On the direct labor efficiency variance (LEV)? Indicate what the new variances would be below. If required, round your answers to the nearest cent.

Direct labor rate variance (LRV): $ _________________ _________________

Direct labor efficiency variance (LEV): $ _________________ _________________
