Answer: t= [tex]\frac{a-800}{200}[/tex]
Step-by-step explanation:
a=800 + 200t
Swap sides so that all variable terms are on the left-hand side.
800+200t=a
Subtract 800 from both sides.
200t=a−800
Divide both sides by 200.
[tex]\frac{200t}{200}=\frac{a-800}{200}[/tex]
Dividing by 200 undoes the multiplication by 200.
[tex]t=\frac{a-800}{200}[/tex]
Divide a−800 by 200.
[tex]t=\frac{a}{200} - 4[/tex]
