The solution does not correctly give the %. Please double check the answer.

Can someone explain to me the difference between case () and case name? Google isn’t turning up anything and this is seemingly missing from my learnings on this site

With this case, we’re creating multiple arguments to create a new column and rows. The CASE() is used to change the data type for an expression. Think of a ‘3.00 off’ integer phrase changed to ‘3.00’ using CASE( ‘3.00 off’ AS REAL). Now the phrase was changed into a number from an integer, and can be used for calculations.


Can someone help me understand step 2 a little further… I’m not sure what’s going on in the second column the pct one… it’s on line 66… I understand what the outcome we’re wanting but a bit lost getting there
