Answer:
Jack earned $2560 this summer.
Step-by-step explanation:
Given:
Money given away = $256
Percentile of money give away = 10%
We need to find the total money he earned this summer.
Solution:
Let the total money he earned this summer be 'x'.
So we can say that;
Money given away is equal to Percentile of money give away multiplied by total money he earned this summer and then divided by 100.
framing in equation form we get;
![\frac{10}{100}\times x = 256\\\\\frac{x}{10}=256](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B100%7D%5Ctimes%20x%20%3D%20256%5C%5C%5C%5C%5Cfrac%7Bx%7D%7B10%7D%3D256)
Now multiplying both side by 10 we get;
![\frac{x}{10}\times 10=256\times 10\\\\x=\$2560](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B10%7D%5Ctimes%2010%3D256%5Ctimes%2010%5C%5C%5C%5Cx%3D%5C%242560)
Hence Jack earned $2560 this summer.
Lets first simplify the dimensions of the rectangle
length = 7
breadth =
![\frac{6}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B10%7D%20)
=
![\frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B5%7D%20)
= 0.6
The area of rectangle = length * breadth
so, area of rectangle = 7 * 0.6
Area of rectangle = 4.2
