It's a story problem so be courteous:

A zookeeper needs to mix a solution for baby penguins so it has the right amount of medicine. Solution A has 20% medicine. Solution B has 4% medicine. How many ounces of each solution are needed to obtain 10 ounces OF 8% medicine?

Good Luck :)

Amount of solution A = x

B = 10 - x

x (.2) + (10-x)(.04) = 10 (.08)

.2x + .4 -.04x = .8

.16x = .4

x = 2.5 oz = amount of A (10-2.5) = B = 7.5 oz

Amount of solution A = x

B = 10 - x

x (.2) + (10-x)(.04) = 10 (.08)

.2x + .4 -.04x = .8

.16x = .4

x = 2.5 oz = amount of A (10-2.5) = B = 7.5 oz
