Hints

US Version

Start by adding up the cost of the entire meal.

UK Version

Start by adding up the cost of all the items on the table.

US Version

Luke's meal cost twice as much as the professor's. That means the ratio of Luke's cost compared to the professor's cost must be 2:1.

UK Version

Luke's meal cost twice as much as the professor's. That means the ratio of Luke's part of the bill compared to the professor's must be 2:1.

US Version

The cost of the entire meal comes out to 105 pounds. This total needs to be split to fit our ratio of 2:1. Therefore, Luke's meal cost 70 pounds and the professor's cost 35.

What combination of food and drink items can you find that add up to 70?

UK Version

The cost of the entire meal comes to £105. This total needs to be split to fit our ratio of 2:1. The sum of the parts of this ratio is 3, so divide the total by 3 to get £35 and the costs come to (2 x £35):(1 x £35). Therefore, Luke's meal cost £70 and the professor's £35.

What combination of food and drink items can you find that adds up to £70?


Solution

Incorrect

Too bad!

Perhaps you aren't going about this quite the right way. Why don't you try a different approach?

Correct

Good work!

US Version

If you calculate the total tab, you'll see that the meal cost 105 pounds. Knowing the total, Luke must have ordered 70 pounds' worth of food, and the professor 35. Once you've got those numbers, the rest is easy.

"Are you sure you didn't order too much?"

"Nope! This stew's great, and this steak's--CHOMP--great too!"

"Well, then...eat up, I suppose."

UK Version

If you calculate the total bill, you'll see that the meal cost £105. Knowing the total, Luke must have ordered £70 worth of food and the professor £35 worth. Once you've got those numbers, the rest is easy.

"Are you sure you didn't order too much?"

"Nope! This (slurp) stew's great and the steak is (chomp) delicious too!"
