Answer 2

Problem Analysis

To solve this problem, we need to calculate the new price of a barrel of oil after it has decreased by 20%. The original price of the barrel of oil is $75.

Calculation

To calculate the new price, we need to subtract 20% of the original price from the original price.

20% of $75 is calculated as follows: ``` 20% = (20/100) * $75 = $15 ```

Subtracting $15 from $75 gives us the new price: ``` $75 - $15 = $60 ```

Therefore, the new price of a barrel of oil after the price decrease is $60.

Answer

The new price of a barrel of oil after it has decreased by 20% is $60.
