Express total in terms of d and p

Let the total cost be represented with T.

Since he pays d out his total earnings, T. Then the expression for p is:

[tex]p = \frac{Contribution}{Earnings}[/tex]

This gives:

[tex]p = \frac{d}{T}[/tex]

Multiply both sides by T

[tex]pT = d[/tex]

Divide both sides by p

[tex]T = \frac{d}{p}[/tex]
