If it was priced at $100 and had 30% off, it would cost
($100 - (30% of $100)) =$70.
If there was an additional 20% off, it would cost
($100 - (30% of $100) - (20% of 30% of $100)) = $56.
So the total savings is (100-56)/100=44%.
For $74.99, the answer is the same but the numbers are slightly different,
(74.99 - (30% of 74.99) - (20% of 30% of 74.99))/74.99 = 44%.
The equation for finding the area of a triangle is (bh)/2.
(The slash is a division sign)
So, with this equation, it would be (19*12)/2.
That would equal 114. So the answer is 114 ft squared.
Answer:
Julie has 6 photos that she wants to rearrange.
Two of them are fixed at the middle position.
=> There are 4 photos left for rearranging.
=> This is the permutation with n = 4, k = 4.
=> The number of ways Julie can arrange the photos:
N = 4 x 3 x 2 x 1 = 24 ways
Hope this helps!
