The output of a plant is 4335 pounds of ball bearings per week (5days) if each ball weighs .0113 g how many ball bearings does t
AfilCa [17]

The plant makes 3.50 × 10⁷ bearings per day

<em>Pounds of bearings</em> = 1 da × (4355 lb bearings/5 da) = 871.0 lb bearings

<em>Grams of bearings</em> = 871.0 lb bearings × (453.6 g bearings/1 lb bearings)

= 3.951 × 10⁵ g bearings

<em>No. of bearings</em> = 3.951 × 10⁵ g bearings × (1 bearing/0.0113 g bearing)

= 3.50 × 10⁷ bearings
