yeah, sure. It is one of your strategy in your arsenal. Of course, you can.
However, picking numbers is one of the most powerful ways to tackle a question yet is not among my favorite.
Often is better working conceptually and reaching faster the solution that waste time with numbers.
It depends.

I agree with this because sometimes there are fractions and decimals and negatives (FR O ZE N) that need to be taken into account and picking whole positive numbers can be deceptive. I use picking numbers strategy mainly when I am unable to work it out conceptually or I am sure that it is a positive integer
hi..
picking a number is a good way to tackle a question easily and with speed.
But as you say it is quite deceptive and you should be careful..
As a rule never substitute a value when two quantities are interlinked..
Here the two values are constant, so you can use it
revenue from 50 = 50A
sponsoring cost = \(\frac{148A}{3}=49.33*A\)
so whatever you take A, revenue and sponsoring cost will have same relationship that is R>S
But say I told you the sponsoring cost was a constant amount 20.
or sponsoring amount was 1$ dollar for each person attending.
here you cannot take a value for admission price
