I need help with this task.
The utility function is U(a;b)=3a+2b. The prices for the goods a and b are equal. Explain what an optional consumption of the consumer would be without calculating.
How do I explain it without math?
Since the prices of a and b are equal, but the consumer gets more utility from a (3a vs. 2b) then the optimal consumption would be to purchase as much of a as possible, and only purchase b if a has run out.
I'd also like to point out it doesn't completely make sense to explain a math equation without math...
