Please be ready for a Math test early to mid next week. Topics will include:
1) Using proportions to solve problems

200 L of water   x 2   =     400 L of water
     15 people     x 2    =     X

How many people can be served with 400 L of water?
X= 30 so 30 people can be served

2) Comparing Rates

36 teabags cost $1.49  or    144 teabags cost $5.59  what's the better deal?

36 x 4 = 144   So the Large pack is 4 times bigger

1.49 x 4 = $5.96   So $5.96- $5.59 = 0.37

So if you buy the large pack, you save 37 cents

3) Calculating percent

What is 1 as a percent ?
            4

4 x 25 =100 so 1 x 25= 25

so 25%

4) Solving problems with percent

5) Tax, discount and commission

6) Simple Interest
