Question 2

Tom and Michael buy ice cream under a promotion. Tom may choose vanilla, mango, strawberry or mint. Michael may choose blueberry, Milo, chocolate or matcha. Each combination costs the amount in the table; for example, vanilla with Milo means both pay USD 3.00 for the ice cream. Which flavour should Tom choose to spend the minimum amount regardless of Michael’s choice?

Interpretation: Use the source’s intended worst-case interpretation: minimize the highest price Tom might have to pay.
