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
34+50+50+50-60+22 You add everything except 60 because deposits mean add money to the account. You subtract 60 because a withdrawal is taking money out of the account. There are three 50s because you deposit $50 each day for 3 days.
