Answer:
A. [tex]p-0.20p\rightarrow 0.80p[/tex]
B. [tex]p+0.20p\rightarrow 1.20p[/tex]
C. [tex]p-\frac{1}{4}p\rightarrow \frac{3}{4}p[/tex]
D. [tex]p+\frac{1}{4}p\rightarrow \frac{5}{4}p[/tex]
Step-by-step explanation:
We have been given 4 expressions. We are supposed to simplify our given expressions.
A. [tex]p-0.20p[/tex]
[tex](1-0.20)p[/tex]
[tex]0.80p[/tex]
Therefore, [tex]p-0.20p\rightarrow 0.80p[/tex].
B. [tex]p+0.20p[/tex]
[tex](1+0.20)p[/tex]
[tex]1.20p[/tex]
Therefore, [tex]p+0.20p\rightarrow 1.20p[/tex].
C. [tex]p-\frac{1}{4}p[/tex]
[tex]\frac{4p}{4}-\frac{p}{4}[/tex]
[tex]\frac{4p-p}{4}[/tex]
[tex]\frac{3p}{4}[/tex]
[tex]\frac{3}{4}p[/tex]
Therefore, [tex]p-\frac{1}{4}p\rightarrow \frac{3}{4}p[/tex].
D. [tex]p+\frac{1}{4}p[/tex]
[tex]\frac{4p}{4}+\frac{p}{4}[/tex]
[tex]\frac{4p+p}{4}[/tex]
[tex]\frac{5p}{4}[/tex]
[tex]\frac{5}{4}p[/tex]
Therefore, [tex]p+\frac{1}{4}p\rightarrow \frac{5}{4}p[/tex].
