A pharmacist receives a prescription for 60 g of a 0.75% w/w bexarotene gel.
How many grams each of a 1% w/w bexarotene gel and gel base must be used
:
percent changed to decimal form: .75% = .0075 and 1% = .01
let x = amt of bexarotene gel
then
(60-x) = amt of base gel
:
.01x = .0075(60)
.01x = .45
x = .45/.01
x = 45 g of 1% gel required
then
60 - 45 = 15 g of gel base
