The whole sales price for a chair is $165. A certain furniture store marks up the wholesalers price by 15%. Find the price of th

vichka [17]

Answer:

$189.75

Step-by-step explanation:

Whenever you want to find the percent of something, you need to turn the percent into a decimal. In this case, we need to find 115% of the wholesale price because there is a markup, so the cost will be higher.

115% as a decimal is 1.15. Here is how the equation will be set up:

$165 • 1.15 = $189.75

No rounding is necessary for this problem because it is already to the nearest cent.

Compare the graphs below of the logarithmic functions. Write the equation to represent g(x).

Neporo4naja [7]

Answer:

The equation to represent g(x) will be $g(x)=log(x)+4$

Step-by-step explanation:

Considering the logarithmic function

$f(x)=log(x)$

As we know that when a constant c gets added to the parent function, the result would be a vertical shift c units in the direction of the sign of c.

So,

$g(x)=log(x)+4$ is basically the shift up by 4 units, and the graph also showing the same situation.

Therefore, the equation to represent g(x) will be $g(x)=log(x)+4$

Also, the graphs of both $f(x)=log(x)$ and $g(x)=log(x)+4$ is attached where black mark graph represents $f(x)=log(x)$ and red mark graph represents $g(x)=log(x)+4$ .
