Question

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 the plant make in a single day

Answer 1

The plant makes 3.50 × 10⁷ bearings per day

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

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

= 3.951 × 10⁵ g bearings

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

= 3.50 × 10⁷ bearings

Answer 2

The number of ball bearings the plant makes in a single day would be 34,802,177

• 4335 pounds of ball bearings are made in 5 days.

• 4335 pounds = 1966323 grams of ball bearings in 5 days

• The quantity of ball bearings per day would be:

                           1966323/5 = 393,264.6 grams.

Each ball bearing weighs 0.0113 grams. Thus, the total number of ball bearings made in a single day can be calculated as:

                       393,264.6/0.0113 = 34,802,177 ball bearings
