Notebooks cost $1.20 each. This weekend they will be $.80 What percentage is the sale?

Answers

In the question it is already given that the actual cost of each notebook is $1.20. For the weekend, the notebooks would sold at a discounted rate of $0.80
he
The amount of discount during the weekend = (1.20 - 0.80) dollars
   = 0.40 dollars
So the amount of discount given during the weekend is $0.40
Now we need to find the percentage of discount given during the weekend.
Then
Percentage of discount during the weekend = (0.40/1.20) * 100
   = 0.33 * 100
   = 33
Then the percentage of discount given is 33%.

The sale is 33% off notebooks. This can be found by first subtracting .8 from 1.2

1.2-.8=.4 Now divide .4 by 1.2 to get your answer.

$(.4)/(1.2)$ =.33

.33=33%

You can also solve this mentally because if you know your basic multiplication tables, 3*4=12 and so $(2)/(3)$ of 12 would equal 8.

Mary has a pink dress, a blue dress, and a yellow dress. She has a black pair of shoes and a white pair. How many dress and shoe outfits can she make?

Answers

There are two ways to solve this.
The first way is logically.
Mary can
-wear a pink dress with black shoes -wear a pink dress with white shoes
-wear a blue dress with black shoes -wear a blue dress with white shoes
-wear a yellow dress with black shoes - wear a yellow dress with white shoes

Count them up, and you'll get six combinations!

Another way is simply mathematically, which is easier in my opinion.

3 (different colored dresses) × 2 (different colored shoes) = 6 (combos)
