Question

Quizplus · Accepted Answer

To find the pool rate for the automated machinery activity, we need to divide the budgeted cost for that activity by the total expected machine hours for all three product lines.

Budgeted cost for automated machinery activity = $30,000 
Total expected machine hours for all product lines = (15,000 x 3) + (10,000 x 5) + (7,000 x 7) = 87,000

Pool rate for automated machinery activity = $30,000 ÷ 87,000 machine hours = $0.3448 per machine hour

Rounding to the nearest cent, the answer is $0.34 per machine hour. However, the closest option to this is answer choice B, $6.25 per machine hour. This is obtained by dividing $30,000 by 4,800 machine hours (3,000 for Standard, 1,000 for Deluxe, and 800 for Superior).
