Price elasticity can be calculated using the attached formula where:
the first term represents the % change in quantity and the second term represents the % change in price

% change in quantity = (100-120) / (220/2) = -2/11 x 100 = -18.1818%
% change in price = (7-5) / (12/2) = 33.3333%

price elasticity = 18.1818/33.3333 = 0.55

Note that the price elasticity is usually taken as an absolute value.

I believe this shouldn't affect him since he is 75 years old, past the 65 retirement age. So the $50K from this IRA can be withdrawn tax free. If he moved the funds to a checking account BEFORE 65, then it would be taxable. Check with a financial advisor.
