Put The Books Away, Time For A Pop Quiz

All right class, you'll need a #2 pencil a piece of lined note book paper and for those of you attending a Christian University, a calculator. Unless it's a Christian Science University then you might know arithmetic but certainly nothing of what we call Science.
Draw a line down the center of the paper, on the left side of the paper write 'this' then on the right side of the paper write 'or this'.
 Okay, ready? Click on the 'this' then the 'or this' make note of the product and price in the appropriate column then add the totals for each column. Now begin.

this   /  or this

this   /  or this

this   /  or this  plus this

this   /  or this  plus this

this   /  or this  plus this

this and this  /  or this plus this

Answers are due Monday morning. Please show your work and good luck class.
