A solution of 75% pesticide is to be mixed with a solution of 51% pesticide to form 48 liters of a 64% solution. How much of the 75% solution is needed?
x=liters of 75%
48-x=liters of 51%
coefficient=percent
75(x)+51(48-x)=64(48)
Distribute
75x+2448-51x=3072
Combine like terms
24x+2448=3072
Subtract 2448 from both sides
24x=624
Divide both sides by 24
x=26
x=liters of 75%
48-x=liters of 51%
Answer:
liters of 75%=26
liters of 51%=22
