Write a SELECT statement that returns four columns based on the InvoiceTotal column of the Invoices table: • Use the CAST function to return the first column as data type decimal with 2 digits to the right of the decimal point. • Use CAST to return the second column as a varchar. • Use the CONVERT function to return the third column as the same data type as the first column. • Use CONVERT to return the fourth column as a varchar, using style 1.

For question 1, i'm a bit stuck between serif fonts or large enough type to read. serif fonts are good fonts to use because their easy to read. but you also need your type be large enough to read. if i had to say what you need to consider most important, i would say d is the answer.  for question 3, i believe the answer is d. it seems most appropriate to do that. on every page or every other page would be too much, and only on the contact page just seems inappropriate.  for question 4, it's probably a. by "color scheme" it doesn't mean just one color, but a set of colors. colors that are complimentary to each other. having too many is too distracting so it's best to limit it as much as possible, but not to the point where your website looks dull.hope this !
