The Average test score start = 100%
It increases by 10%:
100% = 1
10% = 0.10
1 x 0.10 = 0.1
1 + 0.1 = 1.1
It increases by another 15%
1.1 x 0.15 = 0.165
1.1 + 0.165 = 1.265
Remember to move the place value digit to the right two spaces to make it a percentage
126.5% increase is your answer
hope this helps
