At Eady Corporation, maintenance is a variable overhead cost that is based on machine-hours. The performance report for July showed that actual maintenance costs totaled $13,680 and that the associated rate variance was $450 unfavorable. If 7,000 machine-hours were actually worked during July, the standard maintenance cost per machine-hour was:

$1.89 per machine hour

Explanation:

With regards to the above information, we can say that since the associated rate variance is unfavorable, then, that amount must be subtracted from the actual maintenance cost so that we can arrive at the standard maintenance cost.

Standard maintenance cost = $ 13,680 - $450

= $13,230

Also, during July, 7,000 machine hours were actually worked , hence the standard machine maintenance cost per machine hour would be;

= $13,230 / 7,000

= $1.89

Therefore, the cost was $1.89 per machine hour.
