Tia has $ 400 to pay the boat rent. The boat rental fee is $ 150. Soon after paying the rent Tia would have a sum of money equal to $ 250 (400-150 = 250).
With the $ 250 remaining Tia will have to pay the additional for each guest. Each guest will cost aunt $ 15. To know how many guests Tia can invite you only need to divide 250 by 15. The result will be 16.6.
16 people.
400 minus the 150 for the boat and you have $250 left then you dive 250 by 15 to see how many people you can bring and it equals up. To 16.66 people and you can't have half a person so you round it to 16 people
