Answer:
a. $65
b. $(50 + 15x)
Step-by-step explanation:
A. From the question, we are told that the first 2 GB of data costs $50 while the subsequent extra GB cost $15 per GB
so for 3 GB, the normal $50 is charged for the first 2 GB while an extra $15 is charged for the extra 1 GB
so, the total amount charged for 3 GB will be $50 + $15 = $65
B. Amount to be paid in a month where x GB is used over the normal
Firstly, she will pay the $50 , then for the extra she will be paying $15 * x = $15x
So the amount to be paid will be;
$50 + $15x = $(50 + 15x)
Suppose is another solution. Then
Substituting these derivatives into the ODE gives
Let , so that
Then the ODE becomes
and we can condense the left hand side as a derivative of a product,
Integrate both sides with respect to :
Solve for :
Solve for :
So another linearly independent solution is .
Answer:
The price of the tv before tax is 410
Step-by-step explanation:
Let x = price of tv before tax
tax = x* 9%
tax = .09x
The total cost is price of tv before tax plus tax
total cost = x + .09x
total cost = 1.09x
446.90 = 1.09x
Divide each side by 1.09
446.90/1.09 = 1.09x/1.09
410 = x
The price of the tv before tax is 410
