## Example

Alice loves chocolate (X) and strawberries (Y). Her utility is

$$u \left( X, Y \right) = X \times Y$$If Alice has 2 chocolates and 1 strawberry, she gets utility

$$u \left( 2, 1 \right) = 2 \times 1 = 2$$### Question

Alice loves chocolate (X) and strawberries (Y).

Her utility function is `u (X, Y) = X^2Y`.

What is her utility for 9 chocolate and 10 strawberries?

For 9 chocolate and 10 strawberries, Alice's utility is

$$ u \left( 9, 10 \right) = 9^2\times10 = 810 $$
