Respuesta :
a) There is 2.54 quarts in the resulting mixture (b) The percentage of the resulting mixture is 50.8% antifreeze.
Percentage is defined as parts per hundred. Percentage is calculated by dividing the given amount by the total amount and multiplying by 100.
a) 18% of 3 quarts antifreeze contains (18/100) × 3 quarts of antifreeze.
amount of antifreeze = 0 .18 × 3 = 0.54 quarts
Now to this solution 2 quarts of antifreeze is added.
Therefore total amount of antifreeze in the resulting mixture = 2 + 0.54 = 2.54 quarts.
b) Total amount of the resulting mixture = 2 + 3 = 5 quarts
amount of antifreeze in the mixture = 2.54 quarts
Percentage antifreeze in the mixture = (2.54 / 5) × 100 % = 50.8 % .
Therefore there is 2.54 quarts of antifreeze in the mixture and its percentage is 50.8% of the total mixture.
