solution x is 10 percent alcohol by volume , and solution y is 30 percent alcohol by volume . how many milliliters of solution y must be added to 300 milliliters of solution x to create a solution that is 15 percent alcohol by volume ?
n0 = 10.0
n1 = 30.0
n2 = 300.0
n3 = 15.0
t0 = n3 - n0
t1 = n1 - n3
t2 = t0 / t1
answer = n2 * t2
print(answer)
