Answer:
Step-by-step explanation:
3x(x^2+4)
=3x^2+12x
You will have to multiply 600 by 15%
600 x 0.15 = 90
600 + 90 = 690 Euro
The answer to the question
Divide the total the lake holds by the number of days:
400 million / 25 days = 16 million gallons per day.
The amount spent on each tube is $18.5
The total amount spent to rent 15 tubes by the group is $277.50.
Since they did not specify in the question the types of tubes they rented, we cannot determine each types of tubes that the group rented but we can determine the amount spent on each tube provided that they are all the same types.
∴
if 15 tubes = $277.50
1 tube = $x
By cross multiplying:


Therefore, we can conclude that the amount spent on each tube is $18.5
