Question 762944: Please help me solve this question: Amy needs to make 10L of 42% sulphuric acid solution. In the supply room , she finds bottles of 30% sulphuric acid solution and 60% sulphuric acid solution. What volume of each solution should she mix in order to make the 42% solution ?
So far I have the two equations : x+y= 10
0.3x+0.6y=0.42

Amy needs to make 10L of 42% sulphuric acid solution. In the supply room , she finds bottles of 30% sulphuric acid solution and 60% sulphuric acid solution. What volume of each solution should she mix in order to make the 42% solution ?
So far I have the two equations :
x+y= 10
0.3x+0.6y=0.42 ******
The 2nd equation is 0.3x + 0.6y = 0.42*10
-----------
You can use:
x + y = 10
30x + 60y = 42*10
