Part A. Markdown answer = $233.93
$259.92*0.10=$25.992 or $25.99
$259.92 - $25.99 = $233.93 cost after 10% markdown
Part B. Markup answer = $337.90
$259.92 * 0.30= $77.976 of $77.98
$259.92 + $77.98 = $337.90 cost after 30% markup
First answer should be correct ..
I think it is b

Answer:
Step-by-step explanation:
The set {1,2,3,4,5,6} has a total of 6! permutations
a. Of those 6! permutations, 5!=120 begin with 1. So first 120 numbers would contain 1 as the unit digit.
b. The next 120, including the 124th, would begin with '2'
c. Then of the 5! numbers beginning with 2, there are 4!=24 including the 124th number, which have the second digit =1
d. Of these 4! permutations beginning with 21, there are 3!=6 including the 124th permutation which have third digit 3
e. Among these 3! permutations beginning with 213, there are 2 numbers with the fourth digit =4 (121th & 122th), 2 with fourth digit 5 (numbers 123 & 124) and 2 with fourth digit 6 (numbers 125 and 126).
Lastly, of the 2! permutations beginning with 2135, there is one with 5th digit 4 (number 123) and one with 5 digit 6 (number 124).
∴ The 124th number is 213564
Similarly reversing the above procedure we can determine the position of 321546 to be 267th on the list.
84 adults ; I did 108/9 = 12 then 12x7 = 84 because 9-2 = 7 and we wanted to find out the remaining number of people :))
