The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
1) A *the first option*
2)B *the second option*

Step-by-step explanation:
19 * 17 * 20 =6460
If you know the derivative
of some function
, you can tell exactly who
is, up to an additive, constant term. In fact, knowing
, you have

In your case, we have

So, the integral is almost immediate:

So, up to some constant additive term, our function is 
To fix this constant, we know that the function passes through the point (6,10), so we have

And so our function is 
If we want to know when this function equals 6, we simply have to ask
and solve for x, so we have
