t = 
isolate t by dividing both sides by Pr
= t ⇒ t =

Answer:
Option 400p/500-p
Step-by-step explanation:
Let the number of newspaper A sold be 'x'
and the number of newspaper A sold be 'y'
Therefore,
Total revenue = $1x + $1.25y
Total newspapers sold = x + y
Therefore,
according to the question
r =
..........(1)
and,
p = 
or
(x + y)p = 100x
or
y = 
or
y = 
substituting y in 1
r =
or
r = 
or
r = 
multiply and divide the RHS with 4
we get
r = (400p)÷(500-p)
hence,
Option 400p/500-p
