The expression 100+20mgives the volume of water, in liters, in marcel’s pool after marcel spends \[m\] minutes filling his pool. what is the volume of water, in liters, in marcel’s pool after he fills it for 5 1/4 minutes?

A) 225 liters
B) 130 liters
C) 160 liters
D) 205 liters

Answer 1

After plugging in 5.25 minutes for m in the expression 100 + 20m, we find that Marcel's pool will have 205 liters of water, matching answer option D.

Step-by-step explanation:

To calculate the volume of water in Marcel's pool after he fills it for 5 1/4 minutes, we will plug the value of m (which is 5.25 minutes) into the given expression, 100 + 20m.

The calculation will be as follows:

• First, convert 5 1/4 minutes into a decimal, which is 5.25 minutes.
• Then multiply 20 by 5.25 to find out how much water is filled in 5.25 minutes.
• Finally, add the result to the initial volume of 100 liters.

Now let's do the calculation:

1. 20 × 5.25 = 105 liters
2. 100 liters + 105 liters = 205 liters

Therefore, the volume of water in Marcel's pool after 5 1/4 minutes is 205 liters, which corresponds to answer option D.
