Final answer:
Ivanna pumped water into her pool at 2 gallons per minute for 18 minutes, resulting in a total of 36 gallons of water added to the pool. The correct answer is option C) 36 gallons.
Step-by-step explanation:
The question asks to calculate the total change in the amount of water in Ivanna's pool after pumping 2 gallons per minute for 18 minutes. To find the total volume of water pumped into the pool, we use the following multiplication:
Volume pumped per minute × Number of minutes = Total volume pumped
2 gallons/minute × 18 minutes = 36 gallons
Therefore, option C) 36 gallons is the correct answer.
