15% of 20 gal = 0.15 * 20 gal = 3 gal, so the solution contains 3 gal of salt.
If we add <em>x</em> gal of water to the solution, we end up with (20 + <em>x</em>) gal of solution. We want the new mixture to have a concentration of 10%, or
10% of (20 + <em>x</em>) gal = 0.1 * (20 + <em>x</em>) gal = 2 + 0.1<em>x</em> gal
of salt.
The amount of salt in the tank hasn't changed. Solve for <em>x </em>:
2 + 0.1<em>x</em> = 3
0.1<em>x</em> = 1
<em>x</em> = 10 gal

Answer=46 employees
40 employees
15% increase
100%+15%=115%
115%=1.15
40*1.15=46 employees
Answer:
y = -2/1x-2
Step-by-step explanation:
If each unit happens to be 1 then this will be correct, but it is hard to determine the equation without units.
