The expression for y in terms of "a" when value of x is doubled is 
<em><u>Solution:</u></em>
Given that,
y is directly proportional to 
Therefore,


Where "k" is the constant of proportionality
y = a for particular value of x
Therefore,
--------- eqn 1
We have to find when x is doubled
x is doubled means 2x
Let it be 
Hence we get,
--------- eqn 2
Substitute value of k from eqn 1, we get

Thus expression for y in terms of "a" when value of x is doubled is

Answer:
Relative frequency for each discount :
10% - 0.4925, 20% - 0.3325, 40% - 0.175
Since only 33.25% of customers got 20% discount, it is not an appropriate method.
Step-by-step explanation:
relative frequency = number of frequency/total number of frequency
you can find out relative frequency for each number and add them up to get relative frequencies of discounts.
