The price of a tablet was increased from $180 to $207. What was the percent of increase?
Fudgin [204]

Answer:

15%

Step-by-step explanation:

The price of the tablet was increased from $180 to $207.

Increase = $207 - $180

= $27

Therefore,

Percentage increase = increase/initial amount x 100%

That’s $27/$180 x 100%

0.15 x 100

15%

The percentage increase was 15%

lukranit [14]

Answer:

Mean = 55.2

Step-by-step explanation:

Given data set:   113, 14, 23, 12, 114

To find the <u>mean</u> of a data set, <u>divide</u> the <u>sum</u> of all data values by the total <u>number</u> of data values:

\large \begin{aligned}\sf Mean & = \sf\dfrac{sum\:of\:all\:data\:values}{total\:number\:of\:data\:values} \\\\\implies \sf Mean & = \sf \dfrac{113 + 14 + 23 + 12 + 114}{5}\\\\& = \sf \dfrac{276}{5}\\\\& = \sf 55.2\end{aligned}
