Question 619387
 Prepare 240 g of 4% sulfate ointment using a 2% ointment and a 3.5% ointment.
Note: You cannot raise the percentage to 4% when you are using 2% and 3.5% ointment.
------------------------------------

Prepare 180mg of tolnaftate 0.05% cream. In stock, you have 225 g each of tolnaftate 0.10% cream and tolnaftate cream 0.25%.
Equation:
toln + toln = toln
Note: You cannot reduce the percentage of the cream by combining
two creams that are higher percentage.
