Answer:
2,460 liters per hour
Step-by-Step Explanation:
The problem above requires only two operations:<em> multiplication</em> and<em> addition</em>. First, you have to answer this question: <em>How much is 2.5% of 2,400 liters?"</em>
You may do this by<u> multiplying 2,400 by 2.5%.</u>
2,400 x 2.5% (0.025) = 60 liters <em>(this is the amount that the new model can fill more than old model).</em>
Then, you have to<em> add 60 liters to 2,400 liters.</em>
2,400 liters + 60 liters = 2,460 liters
This means that the new model can fill 2,460 liters per hour.
