Answer:
C. shortage of skilled labor.
Explanation:
The invention of high-tech (computers, biotechnology, robots, drones, self driving vehicles and so an) is reducing the involvement of skill human labor which will continue incoming years. For example humans carryout the task of carrying-out calculation several years ago, but in recent years computers carry out such works and at a faster pace. Also routine human works such as arranging, bottling, pasting of labels can be carried-out by well programmed out and trained robots. These and many more will cause the shortage of labor(human) in coming years.
Answer:

Explanation:
Multiple Choices aren't given, so I will just solve this.
Josiah had "d" dimes and "n" nickels.
There are a total of 35 coins, nickels and dimes.
The value of "d" dimes and "n" nickels is $3.30
Note: Value of nickels is 0.05 and dimes is 0.10 (in dollars)
The system of equations (2) we can use to solve this will be:
1) an equation involving total number of coins
2) an equation stating the value of each coin and total value
Equation 1:

Equation 2:

These are the 2 equations that can be solved simulataneously to find the number of nickels and dimes.
Answer:
a. $612
b. $2,480
Explanation:
a. Overhead is applied at a rate of $12 per direct labor hour.
Overhead applied would therefore be;
= 12 * total labor hours
= 12 * 51
= $612
b. Total Cost = Direct labor cost + Direct Material cost + Manufacturing overhead
= 978 + 890 + 612
= $2,480
