Step-by-step explanation:
The number of problems that the math team successfully resolved at this year's competition increased from last year by a factor of ten.
Let number of problems resolved by math team last year be x .
So number of problems resolved by math team this year is 10x.
Percentage increase = ( 10x - x / x) 100
= 900%
