1st possibly the number line
2nd you can draw them on paper
3rd try them at percentage
$1,800 (10%) = $180
jay pays 10% of the expenses beyond the deductible so you multiply the amount beyond the deductible by 10%.
$1,800 - $180 = $1,620
or
$1,800 (90%) = $1,620
you subtract what jay pays from the total or you multiply the total by 90%
jay pays $180 of the expenses past the deductible (not including his $200 deductible) and his insurance company pays $1,620.
The 21 consonants are :
b c d f g h j k l m n p q r s t v w x y z
The 5 vowels are :
a e i o u
Now, to arrange the consonants there are 21! ways.
Now the vowels can be arranged in 22 ways because one vowel can be placed before 'b' and one after 'z' also.
It can be shown like this : (V represents vowels)
V b V c V d V f .......................
Therefor the ways to put vowels will be :
The complete order to place consonants without repeating vowels becomes:
Answer is A m^7/n^2 -----------------
