A. There was a percent decrease of 21.3% from the first to the second day.
B. There was an increase of 21.6% from the second to the third day.
Step-by-step explanation:
Step 1; Shaun collected $925 the first day and $728 in the second day.So there has been a decrease in money collected. Percent decrease is given by dividing the difference in values by the actual value multiplied by 100.
% decrease = (difference in values / initial value) × 100
% decrease = (925 - 728)/ 925 × 100 = 197/925 × 100 = 21.297%.
This is rounded off to 21.3%.
Step 2; We need to calculate the money collected on the third day.
Money collected on the third day = Total money collected in three days - money collected on the first and second day. =$2,538 - ($925 + $728) = $2,538 - ($1,653) = $885.
Step 3; So Shaun collected $728 on the second day and $885 on the third day.So there has been an increase in money collected. Percent increase is given by dividing the difference in values by the actual value multiplied by 100.
% increase = (difference in values / initial value) × 100
% increase = (885 - 728)/ 728 × 100 = 157/728 × 100 = 21.565%.
This is rounded off to 21.6%.
