Answer:
Answer: The value of X is 28
For the first digit, we have 5 options that are 4,5,6,7,8 . For the second digit, we have 4 options which are 3,4,5 or 6 and for the third digit, we have the options of all numbers except 2 or 5 that is 1,3,4,6,7,8,9,0 . SO we have 8 options for third digit . So to find the total number of options, we need to multiply all the possible options for each digit that is 5 times 4 times 8 = 160 . So the number of possible options are 160 .
So if it is 3 for $2 you multiply 2 by 4 because 3*4=12 and that is one dozen.
So the answer you are looking for is 2*4=8. So one dozen is $8.
