Answer:
$48,300
100 + 38% = 138% or 1.38
$48,300 / 1.38 = $35,000
Check:
$35,000 * 1.38 = $48,300
$35,000 * .38 = $13,300 (raise) + salary $35,000 = $48,300

Step-by-step explanation:
I just got it right on PLATO, so I know it’s 100% correct.
Let volume of 4% solution = x and of 14% be y
them x + y = 65........(1) also using the actual weights of salt:-
0.04x + 0.14y = 65*0.06 = 3.9
multiplying the above equation by -25 we have
-x - 3.5y = -97.5 adding this to equation (1)
--2.5y = -32.5
y= 13
and x = 65 - 13 = 52
so we need 13 mls of the 14%, and 52 mls of the 4% solution.
