Problema Solution
A pharmacist has 70 g of a topical cream that contains 65% glycerine. How many grams of the cream are not glycerine?
Answer provided by our tutors
if 65% of the cream is glycerine of 70g, then
70 * 0.65 g must be the part that is not glycerine
then 45.5g is glycerine
so, the total amount of cream that is not glycerine should be 70 - 45.5
which equals to 24.5g
