Apharmacist whishes to mix a solution that is 6% minoxidil. she has on hand 100 ml of 4% solution and wishes to add some 8% solution to obtain the desired 6% solution. how much 8% solution should she add?

100

Step-by-step explanation:

Let x be the amount to be added of the second solution. For every 100ml of it 8 units of minoxidil are added. The total amount of solution will be (100 + x), so the final concentration is given by:

 [Multiplying by (100 + x)]

                           [Transposing terms]

                             [ operating]

                                                [Dividing by 0.02]

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
