Question

An airline charges nothing for a suitcase up to 20 pounds. For every pound over 20, the airline charges $2 per pound (only for pounds over 20). How much does the airline charge for a 35 pound suitcase?

Answer 1

$30

Explanation:

For a 35 pounds suitcase, the airline charges $0 for the first 20 pounds and $2 per pound for the remaining 15 pounds as the airline charges for only pounds over 20

Answer 2

Answer: $30

Explanation: because the airline does not start charging per pound till after 20 pounds, we know that we can take away 20 pounds from the total weight of 35 pounds because we wont be charged for that. That means that we have to pay for 15 pounds. because each pound is worth $2, we have to multiply the remaining 15 pounds by 2 which gives us 30 as our total, meaning that a 35 pound suitcase costs $30. hope this helps :))
