Blog Math and Tissue

Congratulations to the students who completed their blog math on time and with precision.  The correct answer was:
Box 1 - Since one bar is 10%, there are ten bars in the box.  I must divide $7.49 (the cost of the whole box) by ten and that means that each bar is about $0.75 (money only has two digits to the right of the decimal so rounding is necessary).
Box 2 - I must divide $3.75 (the price of box two) by 4 bars which means that the cost of one would be $0.94 (money only has two digits to the right of the decimal so rounding is necessary).

Therefore it is a better deal to buy box one.

Let's take it further this week.  In Ontario, sales tax (GST and PST) is 13%.  Calculate the amount of tax that would be added to each box if the boxes were purchased separately.  What would the total price be to buy one of each? Justify your thinking.

HELP!!! We are all out of tissues and we still have three months together.  If you can spare a box, please send it in.  Thank you very much in advance!

The math test that was originally scheduled for Friday will now be held on Monday April 10.
