Asecret code consist of 3 digits from 0 to 9 followed by 2 letters from ’a’ to ’z’. none of the digits or letters repeat. how many secret codes are possible?

Total number of possible secrets = 468,000

Step-by-step explanation:

total number of places are 5 . out of which 3 places are filled by 10 numbers from 0 to 9 which cannot be repeated therefore

number of choice of filling first place for a number is 10

number of choices of filling second place is 9

number of choices of filing third place is 8

number of choice of filling letters at first place of alphabet = 26

number of choices of filling letters at second place of alphabet =25

therefore total number of possible codes = 10x9x8x26x25

=468,000

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
