Answer:
John has 7 dimes and 13 nickels
Explanation:
let N = nickels
let D = dimes
5N + 10D = 135
N = D + 6
5(D + 6) +10D = 135
5D + 30 + 10D = 135
15D = 135 - 30 = 105
D = 105 / 15 = 7
N = D + 6 = 7 + 6 = 13
Answer:
3.73 years or 4 years approx
Explanation:
The computation of the number of years taken for money invested for double is shown below:
As we know that
Amount = Principal × (1 + interest rate ÷ time period)^interest rate × time period
where,
We assume the principal be P
And, the amount is 2P
And, the other values would remain the same
So,
2P = P (1 + 0.2044 ÷ time period)^ 1 × time period
2 = (1.2044)^ time period
Now take the log both sides
ln2 = ln (1.2044)^time period
ln2 - time period ln (1.2044)
So,
time period = ln(2) ÷ ln (1.2044)
= 3.73 years or 4 years approx
Answer:
7.7 per direct labor hour
Explanation:
Number of direct labor hours = 700,000 / 25
Number of direct labor hours = 28,000 labor hours
Overhead cost = Shop and repair equipment depreciation + Shop supervisor salaries + Shop property taxes + Shop supplies
Overhead cost = 46,100 + 128,300 + 23,300 + 17,900
Overhead cost = 215,600
Predetermined overhead rate = Overhead cost/Direct labor hours
= 215,600 / 28,000 labor hours
= 7.7 per direct labor hour
