What is the volume, in cubic feet, of a rectangular solid that measures 4 feet long, 3 1/2 feet wide, and 2 feet high?

Solution: formula: volume = length x width x height
4 x 2 x 3 1/2 = 28 cubic feet

Solve for x.


3x + 6 -21 = 2x - 4

Solution: x = 10

Anna works in a clothing store and receives a 20% employee discount. If Anna decides to buy a $120 coat, what will her total cost be with 5.5% tax.

solution: In order to solve this problem you must first calculate Anna's 20% discount. Hint: Change the 20% into a decimal. Next, subtract the discount fromthe origional price, this gives you Anna's sale price. Calculate the sales tax, again by changing the percent into a decimal. Finally, add the sale price and sales tax together.


$120 x .2 = $24 (discount)
$120 - $24 = $96
$96 x .055 = $5.28
$96.00 + $5.28 = $101.28 (Anna's final cost)

The sixth line in Pascual's Triangle is 1, 5, 10, 10, 5, 1

Can you figure out the following pattern? 2,5,17....

The pattern is (number) x 4 - 3

Do you understand the number pattern for Pascual's Triangle? If you don't, you are not alone. Up until now, every time I saw it... I had to think about it. And then, I still may not have figured it out... or should I say remembered what the pattern was.

That is, up until now.

The pattern: Each number is just the two numbers above it, added together.

Can you figure out what the next row will be?
