Answer: The number of golf balls is 20000
Step-by-step explanation:

Mass of 1 golf ball = 4 oz
Mass of the sample of golf balls = 2.5 ton = 80000 oz (Conversion factor: 1 ton = 32000 oz)
To find the number of golf balls, we divide the total mass by mass of 1 golf ball, we get:


Hence, the number of golf balls is 20000
