Question

Henly is going over his office supply invoices. On the invoice he checks off 450 ballpoint pens, 15 staplers, and 20 packs of post-it notes. The price of the pens is $.35 each, the staplers are $1.25 each, and the post-it notes are $.50 per pack. How much should the invoice total?

Answer 1

450(.35) = 157.50
15 (1.25) = 18.75
20 (.50) = 10.00

Now just add them..
157.50 + 18.75 + 10.00 = your answer
You can handle it from here :)
