Id say the answer is D i might be wrong tho
The answer is D of the equation
The first letter can be any one of the 26 letters in the alphabet. For each one . . .
The second letter can be any one of the 25 remaining ones. For each one . . .
The third letter can be any one of the 24 remaining ones. For each one . . .
The fourth letter can be any one of the 23 remaining ones.
Total possible 4-letter codes = (26 x 25 x 24 x 23) = <em>358,800 </em>
Remember to use PEMDAS when solving.
= 7 + (5 – 9)2 + 3(16 ÷ 8)
= 7 + (-4)2 + 3(2)
= 7 + (-8) + 6
= -1 + 6
= 5
Best of Luck!
