The group rent 11 river rent tubes and 4 cooler tubes.
Step-by-step explanation:
Rent for river rent tube = $20
Rent for cooler tubes = $12.50
Total spent = $270
Total tubes rented = 15
Let,
x be the number of river rent tube.
y be the number of cooler tubes.
According to given statement;
x+y=15 Eqn 1
20x+12.50y=270 Eqn 2
Multiplying Eqn 1 by 20

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 7.5

Putting y=4 in Eqn 1

The group rent 11 river rent tubes and 4 cooler tubes.
