Answer:
1. $590
2. $9.83
Explanation:
1.
Total Number of Direct Labor Hours:
= Total Labor Cost ÷ Labor Rate Per Hour
= 150 ÷ 15
= 10 Hours
Total Overheads:
= Total Number of Direct Labor Hours*Predetermined Overhead Rate
= 10 × 21
= 210
Total Manufacturing Cost = 230 + 150 + 210
= $590
2.
Average Cost:
= Total Manufacturing Cost ÷ Number of Units
= 590 ÷ 60
= $9.83
Answer:
For more than 180 minutes of phone use.
Explanation:
Let m represent number of minutes of phone use in a month.
We have been given that in Plan A, there is no monthly fee, but the customer pays $0.06 per minute of use.
The cost of using m minutes in plan A would be 
.
We are also told that in Plan B, the customer pays a monthly fee of $4.80 and then an additional $0.03 per minute of use.
The cost of using m minutes in plan B would be 
.
To find the amounts of monthly phone when Plan A will cost more than Plan B, we will set cost of plane A greater than cost of plan B as:
Let us solve for m.
Therefore, Plan A will cost more than Plan B for more than 180 minutes of phone use.
