Final answer:
To find the selling price of an article with a 30% profit, multiply the cost price (₦120.00) by 30% to get the profit (₦36.00), and then add it to the cost price to get the selling price (₦156.00).
Step-by-step explanation:
To calculate the selling price of an article after a profit of 30%, you would follow these steps:
- Calculate the profit by converting the percentage to a decimal and multiplying it by the cost price. In this case, 30% of ₦120.00 is 0.30 × ₦120.00 which equals ₦36.00.
- Add the profit to the cost price to get the selling price. So, ₦120.00 + ₦36.00 equals ₦156.00.
Therefore, the selling price of the article is ₦156.00.
