Answer 1

Price of smartphone in 2013 is $335.153.

Explanation:

We are given the following information in the question.

Price of smartphone in 2012 = $377

Decline percentage of average price of phone from 2012 to 2013 = 11.1%

We have to calculate the the average price of mobile in 2013:

Formula:

Decrease in average price =
`\text{Price of smartphone in 2012}* \text{Decline percent in average price}`

`= \displaystyle(11.1)/(100)* 377\\\\ =41.847\$`

Average price of smartphone in 2013 =
`\text{ Average price of smartphone in 2012 - Decrease in price of smartphone}\\= 377 - 41.847\\= 335.153`

Thus, the price of smartphone in 2013 is $335.153.

Answer 2

$335.15

Explanation:

(2012 price) - 11.1% · (2012 price) = (2013 price)

$377(1 - 0.111) = (2013 price)

$377 · 0.889 = $335.15 = (2013 price)

The average price of that type of smartphone in 2013 was $335.15.
