Each bracelet costs $2.75
She sells them for $7
She makes 7-2.75 = $4.25/bracelet
Let b = # bracelets
To make a profit she has to earn more than $775
4.25b > 775
b > 775/4.25
b > 182 6/17
To make a profit she must sell at least 182 bracelets
The cost for being late is $2.75 because 11 divided by four is 2.75
20% ,since .02 would equal 2%

its 2

Answer:
There can be 14,040,000 different passwords
Step-by-step explanation:
Number of permutations to order 3 letters and 2 numbers (total 5)
(AAANN, AANNA,AANAN,...)
= 5! / (3! 2!)
= 120 / (6*2)
= 10
For each permutation, the three distinct (English) letters can be arranged in
26!/(26-3)! = 26!/23! = 26*25*24 = 15600 ways
For each permutation, the two distinct digits can be arranged in
10!/(10-2)! = 10!/8! = 10*9 = 90 ways.
So the total number of distinct passwords is the product of all three permutations,
N = 10 * 15600 * 90 = 14,040,000
