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
