Answer:

[tex]79.01 + n[/tex]

Step-by-step explanation:

we have

[tex]81.56 + n - 2.55[/tex]

Group terms

[tex](81.56-2.55) + n[/tex]

remember that

[tex](81.56-2.55)=(81+0.56)-(2+0.55)[/tex]

[tex]=(81-2)+(0.56-0.55)[/tex]

[tex]=79+0.01[/tex]

[tex]=79.01[/tex]

substitute in the expression

[tex]79.01 + n[/tex]
