Final answer:
To find the mass of one baseball, subtract the mass of the empty box from the total mass and then divide by the number of baseballs. The calculated mass of one baseball is closest to 144.3 g, which is option A.
Step-by-step explanation:
The student asked: A box of 8 baseballs has a total mass of 1238.4 g. If the empty box has a mass of 89.6 g, what is the mass of one baseball?
To find the mass of one baseball, subtract the mass of the empty box from the total mass and then divide the result by the number of baseballs:
- Total mass of baseballs + box = 1238.4 g
- Mass of empty box = 89.6 g
- Mass of baseballs only = 1238.4 g - 89.6 g = 1148.8 g
- Number of baseballs = 8
- Mass of one baseball = 1148.8 g ÷ 8 = 143.6 g
However, we must consider the answer choices provided and pick the closest one since 143.6 g is not listed:
- A. 144.3 g
- B. 155.1 g
- C. 155.3 g
- D. 144.1 g
The closest match to our calculated mass is option A. 144.3 g.
