Answer: 370 liters
Step-by-step explanation:
Given : Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 8 liters of natural oil for every 5 liters of synthetic oil.
Then , the amount of Petrolyn oil made by above composition =![8+5=13\text{ liters}](https://tex.z-dn.net/?f=8%2B5%3D13%5Ctext%7B%20liters%7D)
Also, the amount of petrolyn oil is proportional to the amount of synthetic oil.
Let x be the amount of synthetic oil need ot make 962 liters of Petrolyn oil, the we have the following equation:-
![\dfrac{x}{962}=\dfrac{5}{13}\\\\\Rightarrow\ x=\dfrac{5\times962}{13}=370](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B962%7D%3D%5Cdfrac%7B5%7D%7B13%7D%5C%5C%5C%5C%5CRightarrow%5C%20x%3D%5Cdfrac%7B5%5Ctimes962%7D%7B13%7D%3D370)
Hence, In order to make 962 liters of Petrolyn oil, 370 liters of synthetic oil is needed .
