Audryn left a $12 tip on a $68.73 restaurant bill. What percent tip did she leave? Round to the nearest tenth of a percent.

Fiesta28 [93]

So, if we take 68.73 to be the 100%, what is 12 in percentage off of it?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
68.73&100\\
12&p
\end{array}\implies \cfrac{68.73}{12}=\cfrac{100}{p}\implies p=\cfrac{12\cdot 100}{68.73}$

seems Audryn is being generous, she probably got the silverware and the maple leaves tablecloth.

Which graph represents the function y = 4?

Temka [501]

Answer:

The first one

Step-by-step explanation:

This is a constant function, i.e. the value for y doesn't depend on x. So, every x value will lead to the same y value, in this case 4.

This implies that the graph is a horizontal line, composed by all points like (x,4), where x can be any value and 4 is fixes as the y coordinate.
