Answer:

62.5 tons.

Explanation:

Let x be the tons of petroleum.

We have been given that we can get 30% of paraffin from some petroleum.

To find the the amount of petroleum we need to figure out x such that 30% of x is 18.75.

We can represent this information in an equation as:


(30)/(100)*x=18.75

Let us solve for x.


0.30*x=18.75

Let us divide both sides of our equation by 0.30.


(0.30*x)/(0.30)=(18.75)/(0.30)


x=62.5

Therefore, we need 62.5 tons of petroleum to get 18.75 tons of paraffin.
