Answer 1

`ᏗᏁᏕᏇᏋᏒ -`

Let's simplify the expression:

`\[1 + 4.25n + (3)/(2)p - 3 + (-2p) + (5)/(4)n\]</p><p>`

Combine like terms:

`\[4.25n + (5)/(4)n = 5.5n\]`

`\[(3)/(2)p - 2p = -(1)/(2)p\]`

Combine constants:

[1 - 3 = -2]

Now the simplified expression is:

`(5.5n - (1)/(2)p - 2\])`

So, the correct option is:

• 
  `a) (5.5n - (1)/(2)p - 2)`
