Shaun collected $925 on the first day of a charity fundraiser. On the second day, he collected $728. By the third day, he had collected a total of $2,538. a) What was the percent decrease in the amount of money collected from the first day to the second day? Round your answer to 1 decimal place. b) Find the percent increase or decrease in the amount cleected from the second day to the third day. Round your answer to 1 decimal place.

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%.
