Answer:

Step-by-step explanation:

P = $ 8,358

r =2.5% = 0.025

t = 14 years

$Amount=P*(1+\frac{r}{100})^{t}\\\\=8358*(1+0.025)^{14}\\\\=8358*(1.025)^{14}\\\\$

how many kilograms of pure water is to be added to 100 kilograms of a 30% saline solution to make it a 10% saline solution

Irina-Kira [14]

Answer:

200 kg

Step-by-step explanation:

If w is the amount of water added, then the concentration of the solution is ...

salt/solute = 100(0.30)/(100 +w) = 0.10

30 = 10 +0.10w . . . . . simplify

20 = 0.10w . . . . . . . . subtract 10

20/0.10 = w = 200 . . . . divide by 0.10

200 kg of water must be added to dilute the solution to 10%.
