Answer:
Step-by-step explanation:
If we let x = the amount of 5% solution and y = the amount of pure alcohol, we can set up that
.05x+y is the amount of alcohol in our resulting mixture, and x+y is the total amount in our resulting mixture (which we know is 380)
so we also know that:
(.05x+y)/380 = .6
If we simplify this we come up with:
.05x+y=228
and we know x+y=380
If we solve this as a system of equations, we will find that:
x=160 ml
y=220 ml
3,950 is your answer. See, you divide 2,370 by 3 to get 1/5 of their goal and then multiply that by 5.
4 (1/2 + 5/4) + -5
4 7/5 + -5
5 3/4 + -5
3/4
Answer:
5040
Step-by-step explanation:
24000-5%=1200
1200+5%=1260
