Determine the cheapest way to the airport. Pupils read a scenario about trying to get 75 people to the airport using two different sizes of taxis. Learners calculate the number of smaller taxis needed given a number of large taxis and the cost for the trip. Scholars then determine which combination of taxis will get them to the airport for the least amount of money.
