If you write a check without enough money in the bank, a certain store will charge you a penalty if the check is returned to them from the bank. The penalty is 5% of the amount of the check plus a $10 processing fee. Let n= the amount of the check and p the amount of the penalty fee. How much was the check if the penalty fee was $16?
I do not know how to figure this out.

okay so set it up as an equation.
first subtract the processing fee from the penalty fee. there fore, fee = 6
we now know that 6 is 5% of the check.
there fore do a ratio to find the answer which = x
6 x
 x  = x= 120
5 100
the check was initally $120
in an equation write:
1610= 6 total fee
then do ratio above don't know how to set up as equation...

sorry the ratio is confusing I cross multiplied 6 by 100 and 5 by x then solved for x. Hope this helps =)

Fee = .05n + 10
so if Fee = 16
16 = .05n + 10
.05n = 6
n = 6/.05 = ....
