Answer 2

Answer:

Step-by-step explanation:

It dependent from your needs, my dear :)

Pencils you need a lot, I assume, but maximum you can buy is 3.

If you make a lot of mistakes, then buy 12 rubbers (I assume it's an eraser).

You don't need much scales ( I assume it's a ruler), unless you are going to fence like a musketeer during the breaks ;) , so buy just 2.

Final count

(3 pencils × 5.00) + (12 rubbers × 0.25) + (2 scales × 1.00) = 20.00
