A 1,280 ounce water cooler in the school office provides water for all of the principals. Each hour, 30 ounces of water is drank from the cooler. Write an equation to show how long until the water in the cooler reaches 0 ounces.(1 point) Responses 1,280 + 30h = 0 1,280 + 30h = 0 30h = 10 30h = 10 1,280 - 30h = 0 1,280 - 30h = 0 10 - 30h = 0

Answer 1

To represent the situation mathematically, we need to show how the amount of water in the cooler decreases over time as it is consumed. Since the cooler starts with 1,280 ounces of water and 30 ounces are consumed every hour, we can create the following equation:

\[ 1280 - 30h = 0 \]

Where:

• \( 1280 \) is the initial amount of water in ounces.
• \( 30h \) is the total amount of water consumed after \( h \) hours.
• The equation is set to zero because we want to find the time when the cooler reaches 0 ounces of water.

So the correct equation is:

\[ 1280 - 30h = 0 \]
