Q. Last semester, Melissa earned an average test score of 8080 points on her math tests. This semester, her average score is 8888 points. What is the percent of increase in Melissa's average test score?\newline____%\_\_\_\_\%
  1. Calculate Increase: Calculate the increase in Melissa's average score from last semester to this semester.\newlineCalculation: 88−80=888 - 80 = 8
  2. Determine Base Score: Determine the original score to use as the base for calculating the percentage increase.\newlineCalculation: Base score =80= 80
  3. Calculate Percentage Increase: Calculate the percentage increase using the formula: (Increase/Original Score)×100(\text{Increase} / \text{Original Score}) \times 100.\newlineCalculation: (8/80)×100=10%(8 / 80) \times 100 = 10\%
