Answer:
Refer to the explanation.
Step-by-step explanation:
Let's take each one at a time.
1.
To solve for the complement, we simply subtract our markup rate by 100%.
100% - 30% = 70%
Now to solve for the selling price, we use the formula
Selling Price = $123.91
2.
We do the same process with the first number.
100% - 40% = 60%
SellingPrice = $366.67
3.
The same as the first two.
100% - 20% = 80%
SellingPrice = $111.88
4.
Now to solve for the markup rate, we use the formula:
In this case we first need to find the markup. The markup is the difference between the selling price and the cost.
Selling Price = $235.28
Cost = $199.99
Markup = $235.28 - $199.99
Markup = $35.29
Now the we know our markup, we can then solve for the markup rate using the formula.
MarkupRate = 0.1499 x 100 = 14.99% or 15%
5.
Now for the last one, we need to find for the cost. Let's use the selling price formula to find for the cost.
Selling Price = $30.77
Complement = 65% or 0.65
This will then give us.
We multiple both sides of the equation by 0.65 to leave our cost alone.
30.77 x 0.65 = Cost
Cost = $20
Answer:
The practical domain of the function is [30,32].
Step-by-step explanation:
The given function is
where, p(h) represents the Vonda's weekly pay as a function of hours worked.
She pays a one time $250 chair rental fee, and earns $40 per hour that she works.
Domain is the set of all possible inputs.
The possible domain of the given function is all real numbers but the number of hours can not be negative, therefore h>0.
It is given that Vonda works between 30 and 32 hours per week at a hair salon. So,
Therefore practical domain of the function is [30,32].
Answer:
The Loan amount at 11 % interest rate is $ 18,500 And
The Loan amount at 9 % interest rate is $ 19,000
Step-by-step explanation:
Given as :
Let The loan given at interest rate of 11 % annual = $ x
And The loan given at interest rate of 9 % annual = ($37,500 - $ x)
Total interest fro both loan = $3745
I.e CI 1 + CI 2 = $3745
Now, From compound interest method :
Or, A 1 = $ 1.11 x
<u>Similarly</u>
Or, A 2 = 1.09 × ($37,500 - $ x)
∵ Compound Interest = Amount - principal
Or, $ 3745 = CI 1 + CI 2
Or, $ 3745 = ($ 1.11 x - $ x) + ( 1.09 × ($37,500 - $ x) - ($37,500 - $ x) )
Or, $ 3745 = $ .11 x+ ($37,500 - $ x) ( .09 )
Or, $ 3745 = $ .02 x + $ 3375
or, 0.02 x = $ 3745 - $ 3375
∴ x = $
SO, x = $ 18,500
And $ 37500 - x = $ 19,000
Hence The Loan amount at 11 % interest rate is $ 18,500 And
The Loan amount at 9 % interest rate is $ 19,000 Answer
