Answer:
[tex]After\ Tax = \frac{p}{1.25}[/tex]
Step-by-step explanation:
Given:
[tex]Before\ Tax =\$ p[/tex]
[tex]After\ Tax =\$ t[/tex]
[tex]p = 1.25t[/tex]
Required
Determine his after tax salary in terms of p
To do this, we simply make t the subject in [tex]p = 1.25t[/tex]
Divide both sides by 1.25
[tex]\frac{p}{1.25} = \frac{1.25t}{1.25}[/tex]
[tex]\frac{p}{1.25} = t[/tex]
[tex]t = \frac{p}{1.25}[/tex]
Substitute p/1.25 for t in [tex]After\ Tax =\$ t[/tex]
[tex]After\ Tax = \frac{p}{1.25}[/tex]
