Answer 1

EXPLANATION

Given the expression

$1+4.25n+\frac{3}{2}p-3+(-2p)+\frac{5}{4}n$

Removing the parentheses:

$1+4.25n\text{ + }\frac{3}{2}p-3-2p+\frac{5}{4}n$

Grouping like terms:

$4.25n+\frac{5}{4}n+\frac{3}{2}p-2p+1-3$

Adding like terms:

$\frac{11}{2}n-\frac{1}{2}p-2$

Representing 11/2 as a decimal number:

$5.5n-\frac{1}{2}p-2$

So, the right option is A.
