Answer:
$40.4
Step-by-step explanation:
The regular price of the fishing rod is $97
There is a 60% discount from that price.
The discount is equal to 60% of $97 which is equal to .60 * $97 which is equal to $58.2
Discount is like a markdown, so subtract $58.2 from the price of the item before the change to get $97 - $58.2 = $38.8
This is the price of the item before tax is applied.
Now you apply the sales tax of 4%.
4% of $38.8 is equal to .04 * $38.8 which is equal to $1.552
Tax is like a markup, so add $1.552 to the price of the item before tax was applied to get a selling price of $38.8 + $1.552 which is equal to $40.352
Round it up and the answer is $40.4
Answer:
x = 3
Step-by-step explanation:
Given in the question an equation,
![2lne^{ln5x}=2ln15](https://tex.z-dn.net/?f=2lne%5E%7Bln5x%7D%3D2ln15)
Step 1
![e^{lnx}=x](https://tex.z-dn.net/?f=e%5E%7Blnx%7D%3Dx)
so,
![2ln(5x)=2ln15](https://tex.z-dn.net/?f=2ln%285x%29%3D2ln15)
Step 2
cancel 2 on both sides of the equation
![ln{5x}=ln15](https://tex.z-dn.net/?f=ln%7B5x%7D%3Dln15)
Step 3
![ln{5x}-ln15=0](https://tex.z-dn.net/?f=ln%7B5x%7D-ln15%3D0)
![ln\frac{5x}{15}=0](https://tex.z-dn.net/?f=ln%5Cfrac%7B5x%7D%7B15%7D%3D0)
Step 4
![ln\frac{x}{3}=0](https://tex.z-dn.net/?f=ln%5Cfrac%7Bx%7D%7B3%7D%3D0)
Step 5
![e^{ln\frac{x}{3}}=e^{0}](https://tex.z-dn.net/?f=e%5E%7Bln%5Cfrac%7Bx%7D%7B3%7D%7D%3De%5E%7B0%7D)
Step 6
x/3 = 1
x = 3(1)
x = 3
Answer:12
Step-by-step explanation:
Let the numbers be a and b
a-3b=5 ........equation (1)
There product is :
ab=68 ..........equation (2)
From equation (1)
a-3b=5
Make a the subject of the formula
a=5+3b. ........equation (3)
Substitute equation (3) into equation (2)
(5+3b)b=68
3(b^2)+3b-68=0
The product is -204b^2(17 and -12)
(b+17)(b-12)=0
b=-17 or b=12
So the number is 12
