One antifreeze solution is 32% alcohol and another is 16% alcohol. How much of each mixture should be added to make 48L a solution that is 27% alcohol ?

Respuesta :

Answer:

33L of 32%

15L of 16%

Step-by-step explanation:

x is the amount of 32% the remainder is 16%, together they make 48 of 27%

32x + 16(48 - x) = 27(48)

distribute

32x + 768 - 16x = 1,296

combine like terms

16x = 528

Divide both sides by 16

x = 33L of 32%

48 - x = 15L of 16%
