Answer:
The state can issue 456,976,000 license plates.
Step-by-step explanation:
For digits, it is assumed that we can use 0-9. Thus, there are 10 options for each slot with a digit.
For letters, it is assumed that we can use the 26 letters of the alphabet (i.e. A through Z). Thus, there are 26 options for each slot with a letter.
For this particular problem, the slot method can be used. Assuming that repetition of letters/digits is allowed:

= 10*26*26*26*26*10*10
=456,976,000.
Therefore, the state can issue 456,976,000 license plates.
Answer: $36
Step-by-step explanation:
Let the total amount of money that he had in the beginning be represented by x.
Since Gary spent 1/6 of his money on baseball cards which was $6. This will then be solved further as:
1/6 × x = 6
1/6x = 6
x = 6 × 6
x = 36
The total amount of money that he had in the beginning was $36
Set this up as a proportion.
400/15 = x/6
Solve for x.
I just hope to help! :)
