A car was sold 24 standard washed in a day , which was 25% of their total sales for that day . What was the total amount of wash

-Dominant- [34]

Answer:

$96$

Step-by-step explanation:

GIVEN: A car was sold $24$ standard washed in a day , which was $25\%$ of their total sales for that day.

TO FIND: Total amount of washes that the car wash sold that day.

SOLUTION:

Let the total sales of car washes sold for that day $=x$

total number of standard car washes sold $s=24$

As, total standard car washes sold are $25\%$ of total sales in a day

$s=\frac{25}{100}x$

putting value in equation

$24=\frac{25}{100}x$

$x=\frac{24}{25}\times100$

$x=96$

Hence the total number of car washes sold that day are $96$

When given a graph, the vertical line test can be used to determine functionality. Describe the vertical line test and explain t

diamong [38]

Answer:

The vertical line test is a way for you to see if a graph represents a function. It allows you to identify if any x values have more than one y value.

A graph would be a function if every input (x) has exactly one output (y). A graph would not be a function if an input (x) has more than one output (y).

Step-by-step explanation:

In a function, every input within the domain of the function must have exactly one output. If the graph has an input that has more than one output, then it is not a function. The vertical line test is what allows you to see if a graph is a function or not.

2 rooms would be 62+42 which is 104

3 rooms would be 104+42 which is 146

4 rooms would be 146+42 which is 188

5 rooms would be 188+42 which is 230

6 rooms would be 230+42 which is 272

but these are the prices including the 20$

without the 20$ the prices would be

2 rooms is 84

3 rooms is 126

4 rooms is 168

The losing candidate in a mayoral election received 10,200 votes, which represented 30% of all votes cast in the election.

ElenaW [278]

well, in the election, the losing candidate received 10200 votes, and we know that's 30% of the whole votes cast, le's say the whole amount is "x" or namely 100%.

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 10200&30\\ x&100 \end{array}\implies \cfrac{10200}{x}=\cfrac{30}{100}\implies \cfrac{10200}{x}=\cfrac{3}{10} \\\\\\ 102000=3x\implies \cfrac{102000}{3}=x\implies 34000=x$

Dorian's 3060 is really 30% of 10200, however, the losing candidate received 30% of the total votes cast, and that is 10200, so Dorian mistakenly is using 30% of the 30% received by the losing candidate as point of reference for her total.
