Step-by-step explanation:
Answer: He made 110 kilograms of 9.09% salt solution.
Step-by-step explanation:
Given: Mass of water= 100 kg
Mass of salt= 10 kg
Total mass of the solution: 100kg+10kg= 110 kg
The percent of salt in solution=
∴The percent of salt in solution
Therefore, He made 110 kilograms of 9.09% salt solution.
Responda:
R $ 15.600
Explicação passo a passo:
Deixe a dívida inicial = x = 100%
% pago = 20% = 0,2x
% esquerda =. 100% - 20% =. 80% = 0,8x
35% da dívida restante = 0,35 * 0,8x = 0,28x
Conseqüentemente,
0,28x = 4368
x = 4368 / 0,28
x = R $ 15.600
Logo, o valor inicial da dívida = R $ 15.600
