Finding the percent increase, it is found that the correct option is given by:

C. The Master Program and the Excel Program are both effective, but Math is more effective because of the greater percent increase.

What is the percent increase?

The percent increase is given by the difference between the final and the initial score, divided by the initial score and multiplied by 100%.

Researching the problem on the internet, we have that:

  • In the Master program, the average score increased from 75 to 87.
  • In the Excel program, the average score increased from 73 to 81.

The percent increases are given as follows:

  • M = 12/75 x 100% = 16%,
  • E = 8/73 x 100% = 10.96%.

Hence the correct option is given by:

C. The Master Program and the Excel Program are both effective, but Math is more effective because of the greater percent increase.
