Answer:
62.5 tons.
Step-by-step 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:
[tex]\frac{30}{100}*x=18.75[/tex]
Let us solve for x.
[tex]0.30*x=18.75[/tex]
Let us divide both sides of our equation by 0.30.
[tex]\frac{0.30*x}{0.30}=\frac{18.75}{0.30}[/tex]
[tex]x=62.5[/tex]
Therefore, we need 62.5 tons of petroleum to get 18.75 tons of paraffin.
