The associative property of addition is being demonstrated here. The parenthesis are moved around to "associate" or "group" the values into two different pairs.
Note: the associative property of multiplication is very similar and it is
a*(b*c) = (a*b)*c<span />
<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
