Answer:
The answer to this question is $56.
Explanation:
In this question the consumption will initially increase by 56 because when we take 30 percent of the $100 it will give the $30. and when we less the money then the amount will be $70. after multiply the value by 0.8 it will give the 56.0. so the answer of the question is $56.
Example:
100*30/100=30
100-30=70
70*0.8=56.0.

Answer:
Potassium ion
Explanation:
The answer is potassium ion.
The use of flame test is to detect the presence of metal ions in the solution. Different metal ions exhibits different colors when they are put into flames.
Sodium ion when subjected to fire or flame produces yellow flame.
Calcium ions and lithium ions produces red flames.
Potassium ions produces violet or purple flames when put to fire.
The color of the flame of each ion depends on the atomic spectrum of the element.
Thus the answer is Potassium ion.
