Answer: 676

Step-by-step explanation:

The total number of letters in English alphabet {From A to Z} = 26

We assume that the repetition of letters is allowed.

If we fix H at the first position , then the number of ways to make three-letter strings that begin with H is given by :-

$1\times26\times26=676$

Hence, the number of ways to make three-letter strings that begin with H is 676.

Answer:

For radio = $40.43

Television = $444.73

Player = $364.73

Step-by-step explanation:

The computation of the each device cost is shown below:

let us assume the following things

radio be x

television x + 10x

player x + 10x - $80

Now the equation is

x + x + 10x + x + 10x - $80 = $850

3x + 20x - $80 = $850

23x = $930

x = $40.43

For radio = $40.43

Television = $40.43 + 10(40.43)

= $40.43 + $404.3

= $444.73

and, the player would be

= $444.73 - $80

= $364.73
