A total of 42 gallons of a glycol solution needs to be added to a heating water loop to ensure the water does not freeze if there is a heating equipment failure. The glycol solution comes in 1.75 -gallon cans. How many cans will be needed? Your answer should be a whole number. A total of \( \square \) cans of glycol will be required.

To find out how many cans of glycol solution are needed, divide the total gallons required by the amount in each can. So, \( 42 \text{ gallons} \div 1.75 \text{ gallons/can} = 24 \text{ cans} \). Therefore, you will need a total of 24 cans of glycol solution. Glycol solutions are often used in various industries because they not only lower the freezing point but also raise the boiling point of water, making them ideal for heating systems. This is especially critical in places where temperatures can suddenly drop, ensuring that equipment operates safely and efficiently without downtime.
