Answer: 14 gallons
Step-by-step explanation:
Let's call the total gallons of gas Abdul's tank can hold <em>x</em>.
Then, based on the information given in the problem, you can write the following expression:
![\frac{1}{5}x+7=\frac{7}{10}x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7Dx%2B7%3D%5Cfrac%7B7%7D%7B10%7Dx)
Therefore, when you solve for x, you obtain the following result:
![\frac{1}{5}x+7=\frac{7}{10}x\\\\\frac{1}{5}x-\frac{7}{10}x=-7\\\\-\frac{1}{2}x=-7\\\\-x=(-7)(2)\\x=14](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7Dx%2B7%3D%5Cfrac%7B7%7D%7B10%7Dx%5C%5C%5C%5C%5Cfrac%7B1%7D%7B5%7Dx-%5Cfrac%7B7%7D%7B10%7Dx%3D-7%5C%5C%5C%5C-%5Cfrac%7B1%7D%7B2%7Dx%3D-7%5C%5C%5C%5C-x%3D%28-7%29%282%29%5C%5Cx%3D14)
"return on investment" is the best measure of the efficiency of an investment, but it should be noted that there are other indicators of how well an investment is doing.
54,273 = A * 1.70^6 where A is the initial number
A = 54273/1.70^6 = 2248
