Step-by-step explanation:
ANSWER:
She should use 30 ounces of water and 180 ounces of 35% salt.
SOLUTION:
First, let us set up a table and fill in the unknowns with variables x and y.
component Unit Value Amount( ounces) value
0% salt 0.0 x 0.0x=0
35% salt 0.35 y 0.35y
Total Mixture 0.3 210 0.3×210=63
From this, we can easily set up the two equations.
Sum of values of two salts = Value of mixture
0x+0.35y = 63 ................(1)
0.35y = 63
y = 180
Now,
Sum of amounts of each salt = Amount of mixture
x + y = 210 ---------> (2)
so, put y = 180 in (2)
x + 180 = 210
x = 210 – 180
x = 30
Hence, she should mix 30 ounces of water and 180 ounces of 35% salt.
