Answer: 120-x
Explanation:
So for how many grams of 25% syrup it will be 120-x because the some amount + x = 120 grams of 15% syrup
so 120-x = the some amount of syrup.
This will be the answer for the problem you were asking for
If you have 6 parts keep scrolling since I will supply some more answers
Next part: How much pure sugar is in the 25% syrup?
For the amount of pure sugar there is in the 25% syrup
that will equal 0.25(120-x) = 30-0.25x
Next: How much sugar is in 120 grams of 15% sugar syrup?
10% of 120 is 12
5% = 12/2 = 6
12+6 = 18
Now the earlier stuff from the problem will come in handy
use the previous answers to write an equation
0.25(120-x)+0.10x=18
= 30-0.25x+0.10x=18
30 -0.15x=18
Now the final part to solve the equation and find the 10% solution and the 25% solution
-0.15x=18-30 = -12
-0.15x=-12
x= -12/-0.15
x=80
the problems not done yet though
we need to find the 25% solution
25% solution = 120-x and x = 80
120-80 = 40
The 10% solution is 80 grams and the 25% solution is 40 grams
