Answer: the percent decrease in accidents is 70%
Explanation:
If a manufacturer reduces the number of in the job accidents from an average of 20 a month to an average of 6 a month, it means that the amount by which the number of in the job accidents reduced is
20 - 6 = 14
The percent decrease is expressed as
decrease in the average number of accidents/ initial average number of accidents × 100
= 14/20 × 100
= 70%
