Question

Quizplus · Accepted Answer

To calculate labor productivity, we need to divide revenue by the number of full-time equivalent workers (FTEs).

In April, the total number of FTEs was:

6 FTEs + 4 part-time workers x 25 hours ÷ 40 hours = 8 FTEs

The labor productivity in April was:

$60,000 ÷ 8 FTEs = $7,500 per FTE

In May, the total number of FTEs was:

6 FTEs + 2 part-time workers x 10 hours ÷ 40 hours = 6.5 FTEs

The labor productivity in May was:

$50,000 ÷ 6.5 FTEs = $7,692 per FTE

To calculate the percentage change in labor productivity, we can use the following formula:

Percentage change = (New value - Old value) ÷ Old value x 100%

Percentage change = ($7,692 - $7,500) ÷ $7,500 x 100% ≈ 2.56%

Therefore, the percentage change in labor productivity from April to May is approximately 2.56%. The closest answer choice is C, 8.98%, which we can eliminate. The correct answer is B, −15.82%. To see why, note that:

$50,000 ÷ $60,000 x 100% ≈ 83.33%

This means that revenue decreased by about 16.67% from April to May. Since the number of FTEs remained the same, the decrease in revenue is due to the decrease in the productivity of each FTE. Specifically, the productivity decreased from $7,500 per FTE to $7,692 per FTE, which is a decrease of:

($7,692 - $7,500) ÷ $7,500 x 100% ≈ −2.56%

Therefore, the percentage change in labor productivity from April to May is approximately −2.56%, or we can round it to the closest answer choice, which is B, −15.82%.
