Answer 3

Calculation of Percentage Overachievement

To calculate the percentage by which the students exceeded their obligation, we can use the following formula:

Percentage Overachievement = ((Amount Collected - Obligation) / Obligation) * 100

Given that the students were obligated to collect 120 tons of scrap metal and they collected 138 tons, we can substitute these values into the formula:

Percentage Overachievement = ((138 - 120) / 120) * 100

Calculating this expression, we find:

Percentage Overachievement = (18 / 120) * 100 = 15%

Therefore, the students exceeded their obligation by 15%.
