Ms. maryna has 10 lbs of 25% sugar syrup. how much sugar does she need to add to make 40% sugar syrup?

The answer is, 2.5

Step-by-step explanation:

Multiply each pairs:

25%*10=250

Since Adding sugar mean that its concentration is 100%.

100%*x=100x

All of that equals to 40(10+x)

so, the equation is,

250+100x=400+40x

Do the equation and you are left with 2.5 as an answer.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

the answer is 62.8 cubic units
