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?

This question appears to be off-topic. The users who voted to close gave this specific reason:

  • "This question does not meet the standards for homework questions as spelled out in the relevant meta posts. For more information, see our policy on homework question and the general FAQ." – Giskard, Herr K., optimal control, Adam Bailey, Kitsune Cavalry


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...

  • $\begingroup$ Thank you! So I just need to look at the coefficients, right? Can the graph help me as well? I know it makes no sense without calculating what that is what the task is. $\endgroup$ – Felix Nov 15 '17 at 8:53
