Question

A spice mixture is 25% thyme. How many grams of thyme must be added to 12g of the mixture to increase the thyme content to 40%?

Answer 1

you have 12 grams of 25% or

12(.25)

and you will add an unknown amount of pure thyme

x(1.00)

and this will make (12 + x) grams of 40% or

(12+x)(.40)

put these together

12(.25) + x(1) = (12+x)(.40)

and solve for x ...
