If an amount of $100 in a savings account increases by 10% , then increases by 10% again, is that the same as increasing by 20% explain.

No becuase when you get ten percent the 1st time you add it to the $100 then you have $110 so then you gain ten percent the second time and it would give you $121 but if you just did swenty percent it would be $120
