A45 gm tube of 1% clotrimazole cream is combined with 15gm of base. what is the new % strength ?

0.75 %

Step-by-step explanation:

Given,

A 45 gm tube of 1% clotrimazole cream is combined with 15gm of base.

Since, the percentage of clotrimazole cream in base = 0 %,

Let x be the percentage of clotrimazole cream in the resultant solution,

So, we can write,

1 % of 45 gm + 0 % of 15 gm = x % of (45 + 15) gm
