Calculator Mistake?Number Theory Level 3
When I questioned the cashier about it, he agreed that he had multiplied the prices together, but said that in this case it didn't matter since the sum of the four items was also $7.11.
What was the price of the most expensive item (in dollars)?
Note: Each item costs a whole number of cents. For example, $2.11 is 211 cents, which is a whole number.
