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.
