Question

From some petroleum, you can get 30% of paraffin. How much petroleum do you need in order to get 18.75 tons of paraffin?

Answer 1

you would have to do 18.75/30%
=75/4*100/30=125/2

Answer 2

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.
