Question 296788
A 1-quart bottle full of liquid is 10% alcohol and a 3-quart bottle full of liquid is 30% alcohol.
If the two bottles are combined,what is the percentage of alcohol in the mixture?
:
let x = the percentage of the resulting mixture
:
10(1) + 30(3) = x(1 + 3)
:
10 + 90  = 4x
x = {{{100/4}}}
x = 25%
