Today Mr Harbeck told us to pick any percent questions and answer them, so here we go.

**Pg 148**

2)How can you calculate a cost of an item with tax just in one step.

In my opinion

*I would multiply the original number by a single percent greater than 100.*

e.g. 111% of 100=1.11 x 100

=111

**Pg 146**

2) gst is 5%, pst is 7% and you purchase an item for $100.

a) How would you represent the 5% and 7% on a 100 grid.

Since it's out of 100 I would just color 5 squares representing 5% and 7 squares representing 7%.

b)How much is the gst and the pst.

Since it's out of 100 the gst would be .07 cents and the pst would be .05cents. The reason I thought this is because 7% and 5% wouldn't be $7 and $5 worth of tax so that's why I turned it into cents.

c)How much tax does a person pay all together.

A person would have to pay 12% worth of tax all together.

5)

a)Describe 2 ways you could calculate the total tax of an item.

First way is by using a ratio table. The second way is by using the formula where you multiply the original number by a single percent greater than 100.

b)Which method do you prefer to use? Explain.

I prefer the ratio table method because, it's the method I'm most used to.

I chose to do this question because my computer wasn't showing all the questions I had chosen.

Great job bruce
