Reply:So that means we'd have 6 ounces of golden poppy. If you take 20 oz. of 25% golden poppy seed mix, that's five ounces. We need one more ounce, from 10% golden poppy seed mix. Well, of course, that's A) 10 oz. of 10% golden poppy seed mix.
Reply:a.10 oz
Reply:Let x be the amount of 10%

Let 30-x be the amount of 25%

x(0.10) + (30-x)(0.25) = 30(0.20)

0.10 x + 30(0.25) - 0.25x = 6

-0.15x = 6 - 7.5 = -1.5

x = (-1.5)/(-0.15) = 10 ounces

Let x ounces of 10% should be mixed with 30-x oz of 25% to make 30oz of 20% of golden poppy seeds

According to the problem,

0.10x+0.25*(30-x)=0.20*30

0.10x+7.50-0.25x=6

-0.15x=6-7.50= -1.50

x= -1.50/-0.15=10

Therefore 10 0z of first quality is to be mixed with 20 oz of second quaity

Option A is the correct choie
Reply:my answer is (A)



.10x + .25(30-x) = 30(.20)

.10x + 7.5 - .25x = 6

- .15x = -1.5

x = 10

Reply:let the amount of 10% poppy = x ounces



the amount of 25% poppy = 30 - x



x*(10/100) + (30-x)*(25/100) = 30*(20/100)



10x/100 + 750/100 - 25x/100 = 600/100



15x = 150



x = 10 ounces
Reply:A - 10 oz just guessing
