The output of a plant is 4335 pounds of ball bearings per week (five days). If each ball bearing weighs 0.0113 g, how many ball bearings does the plant make in a single day? (Indicate the number in proper scientific notation with the appropriate number of significant figures.)

1.69 * 10² ball bearings

Explanation:

The output of a plant is 4335 pounds of ball bearings per week (five days). The output of the plant per day is:

4335 lb/5 day = 867.0 lb/day

1 pound is equal to 453.592 grams. The mass in grams made each day is:

867.0 lb/day * (453.592 g/1 lb) = 1.911 g/day

Each ball bearing weighs 0.0113 g. The number of ball bearings made each day is:

1.911 g/day * (1 ball bearing/0.0113 g) = 1.69 * 10² ball bearing
