Mallorie has $3 in her wallet. if this is 10% of her monthly allowance, what is her monthly allowance?

Her monthly allowance is $30! hope this helped

So its 10% of __ is 3
so we have to divide 3 by .1 because 10% as a decimal is .1(move two decimal places).  

10% of 30 is 3
to check the .1 times 30 is 3

Then why is the question on here if you know the answer
