Answer:
Results are below.
Explanation:
<u>To calculate the direct labor rate and efficiency variance, we need to use the following formulas:</u>
Direct labor rate variance= (Standard Rate - Actual Rate)*Actual Quantity
Direct labor rate variance= (17.7 - 17.8)*7,600
Direct labor rate variance= $760 unfavorable
Actual rate= 135,280/7,600= $17.8
Direct labor time (efficiency) variance= (Standard Quantity - Actual Quantity)*standard rate
Direct labor time (efficiency) variance= (4*1,800 - 7,600)*17.7
Direct labor time (efficiency) variance= $7,080 unfavorable
This test that Albert Chong and his colleagues carried out was most relevant for evaluating the allocative efficiency of these postal services because the test was designed to measure how often and how quickly the letters sent were returned to sender.
Answer:
n= 39.49 years
Explanation:
Giving the following information:
Present value (PV)= $2,600
Future value (FV)= $4,375
Interest rate (i)= 0.33/100= 0.0033
<u>To calculate the number of years, we need to use the following formula:</u>
n= ln(FV/PV) / ln(1+i)
n= ln(4,375/2,600) / ln(1.0033)
n= 157.96/4
n= 39.49 years
