Answer:

90 arrangements

Step-by-step explanation:

Since there are no repititions of letters, there are unique  10 letters in total.

THe number of arrangements would be 2 permutation 10. We need the formula for permutation. That is:

nPr=\frac{n!}{(n-r)!}\\

Now, n = 10 [total] and r is 2, so we have:

nPr=\frac{n!}{(n-r)!}\\\\_{10}P_{2}=\frac{10!}{(10-2)!}\\=\frac{10!}{8!}\\=\frac{10*9*8!}{8!}\\=10*9\\=90

So, there can be 90 arrangements

Lorico [155]

Answer:

  $356.00

Step-by-step explanation:

If d represents the discounted price, and p is the original price, you have ...

  d = p - 20% × p = p(1 -20%) = 0.80p

Then the original price is ...

  p = d/0.80 . . . . . divide by the coefficient of p

  p = $284.80/0.80 = $356.00

The price before the discount was $356.00.
