Challenge #1 - Part 4 Task Now that you have the discount_pct, use your code from that calculation and multiply it by the original_price to see if it matches the discount_amount you calculated . Again, do this calculation in a new column and name the column check. Want a hint? For this new column, use the same code that you used for the last column, but multiply it by the original_price field. Remember, you cannot reference a column name (like discount_amount) within the same query, so you will have to copy the calculation you used previously. Be careful of parentheses! 4/5 567843 AS discount_pct from retail.products Where current_price < original_price product_id sku original_price current_price on_markdown discount_amount discount_pct 67 SC-BLK-8 2
Now that you have the discount_pct, use your code from that calculation and multiply it by the original_price to see if it matches the discount_amount you calculated . Again, do this calculation in a new column and name the column check.
I need step-by-step instructions to know how to add the new column check as asked in Challenge #1 - part 4.
