Naeem weighs different salad takeout containers. The containers respectively weigh 4.5 ounces, 5.01 ounces, 5.3 ounces, 4.75 ounces, and 4.9 ounces. Which is the best whole number estimate of how much all the containers weigh together?

The total weight is given by 4.5 + 5.01 + 5.3 + 4.75 + 4.9 = 24.46

The value 24.46 is in between two whole numbers; 24 and 25

The value 24.50 onwards would have been rounded up to 25

The value 24.46 is rounded down to 24 to the nearest whole number
