alculating 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 $18$ minutes and $6\mathrm{.}2$ quarts of oil are used. In June, Guillermo's Oil and Lube had $990$ 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: $990$

Actual number of direct labor hours worked: $289$ hours

Actual rate paid per direct labor hour: $$15\mathrm{.}00$

Standard rate per direct labor hour: $$14\mathrm{.}00$

Required:

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