Answer:
a. 5.18%;
b. 10.12%;
c. 6.32%;
d. 9.22%.
Explanation:
We apply the formula of Annual rate of return to calculate for the four cases.
The formula for calculating annual rate of return as below:
Annual rate of return = ![\sqrt[year]{Ending value/Beginning value}](https://tex.z-dn.net/?f=%5Csqrt%5Byear%5D%7BEnding%20value%2FBeginning%20value%7D)
-1 ;
So, for each of the case given, by applying the formula, the detailed calculations for each case will be:
+ For case a :
![\sqrt[12]{769.5/420} -1](https://tex.z-dn.net/?f=%5Csqrt%5B12%5D%7B769.5%2F420%7D%20-1)
= 5.18%;
+ For case b:
![\sqrt[14]{11,567.45/3,000} -1](https://tex.z-dn.net/?f=%5Csqrt%5B14%5D%7B11%2C567.45%2F3%2C000%7D%20-1)
= 10.12%;
+ For case c:
![\sqrt[20]{110,000/32,303.47} -1](https://tex.z-dn.net/?f=%5Csqrt%5B20%5D%7B110%2C000%2F32%2C303.47%7D%20-1)
= 6.32%;
+ For case d:
![\sqrt[40]{1,100,000/32,275.63} -1](https://tex.z-dn.net/?f=%5Csqrt%5B40%5D%7B1%2C100%2C000%2F32%2C275.63%7D%20-1)
= 9.22%.
The question that cannot be answered based on the information in the delivery truck data base is 2) What is the average number of customer deliveries made by each truck on a particular day?
<h3>Why can this question not be answered?</h3>
In order to answer this question, the number of customers that each truck delivered to during the day needs to be recorded.
The total number of deliveries will then be added up and divided by the number of trucks making deliveries.
The information on the number of deliveries made is not in the database so this question cannot be answered.
In conclusion, option 2 is correct.

Answer:
(a) $500
(b) $620
(c) $180
(d) $72
Explanation:
Explicit costs refers to the which are incurred during running the business and these costs affects the profitability of the company.
Implicit costs refers to the opportunity cost of selecting some other alternative.
(a) Here, the explicit cost is the cost of purchasing materials = $500
(b) If I rent an electric saw, then the explicit cost is as follows:
= Purchasing cost of material + (Rent × No. of hours to build ramp)
= $500 + ($20 × 6 )
= $500 + $120
= $620
(c) If I use a handsaw, then the implicit cost is as follows:
= Hours to build ramp × A job pays $12 per hour
= 15 × $12
= $180
(d) If I rent an electric saw, then the implicit cost is as follows:
= Hours to build ramp × A job pays $12 per hour
= 6 × $12
= $72
