The area of smaller mp3 player is 4.5 square inches
<em><u>Solution:</u></em>
Given that ratio of corresponding side lengths of two similar MP3 players is 4:3
The area of the larger MP3 player is 8 square inches
<em><u>To find: area of the smaller MP3 player</u></em>
If two MP3 players are similar, then their corresponding sides are proportional.
To find the area ratios, raise the side length ratio to the second power
![\frac{\text {area of larger mp3}}{\text {area of smaller mp3}}=\left(\frac{4}{3}\right)^{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%20%7Barea%20of%20larger%20mp3%7D%7D%7B%5Ctext%20%7Barea%20of%20smaller%20mp3%7D%7D%3D%5Cleft%28%5Cfrac%7B4%7D%7B3%7D%5Cright%29%5E%7B2%7D)
From given information,
area of larger mp3 = 8 square inches
Let the area of smaller mp3 = x
So the above ratio becomes,
![\frac{8}{x}=\left(\frac{4}{3}\right)^{2}\\\\\frac{8}{x} = \frac{16}{9}\\\\16x = 9 \times 8\\\\16x = 72\\\\x = 4.5](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7Bx%7D%3D%5Cleft%28%5Cfrac%7B4%7D%7B3%7D%5Cright%29%5E%7B2%7D%5C%5C%5C%5C%5Cfrac%7B8%7D%7Bx%7D%20%3D%20%5Cfrac%7B16%7D%7B9%7D%5C%5C%5C%5C16x%20%3D%209%20%5Ctimes%208%5C%5C%5C%5C16x%20%3D%2072%5C%5C%5C%5Cx%20%3D%204.5)
Thus the area of smaller mp3 player is 4.5 square inches

<h3>What is
percentage?</h3>
- In mathematics ,a percentage is a number that can be expressed as a fraction of 100.
- If you need to calculate the percentage of a number, divide the number by the whole number and multiply by 100.
- Percentages therefore mean 1 in 100. If you need to convert a decimal number like 0.57 to percent just multiply by 100 So 0.57 x 100 = 57. So as a percentage, 0.57 equals 57%.
- Percentage can be calculated by dividing the value by the total and multiplying the result by 100. The formula used to calculate the percentage is (value/total) x 100%.

This is the concept of algebra, we solve the question as follows:
The cost of renting a camping tent is y
The number of days is x
cost is proportional to number of days, thus:
yαx
y=kx
where k is the constant of proportionality.
If y=$56 when x=7 days, then:
56=7k
hence:
k=56/7=8
therefore:
y=kx will be:
y=8x
the equation in slope intercept form which is y=mx+c is y=8x. In our case c=0 because there was no initial payments required to rent apart from the daily charges.
