240÷15=16 seats at each table
Since there were 15 tables and 240 in total you have to divide to find the number of seats at a table
<u>Answer:</u>
The number of each type of tube does the group rent is 11 tubes for person and 4 “cooler” tubes to carry food and water
<u>Explanation:</u>
The rents for tubes for a person to use = $20
The rents for “cooler” tubes to carry food and water = $12.50.
The rent for a total of 15 tubes = $270
11 tubes whose rent cost $20 =
= 220
4 “cooler” tubes rent cost $12.50 =
= 50
Therefore for 15 tubes = 11 +4= 15
cost = 220 + 50
=270
The number of each type of tube does the group rent is 11 tubes for person and 4 “cooler” tubes to carry food and water
