The gorgeous gown shop had a no tax added sale of dresses. Ginny was so excited that she bought n dresses at $n each, paying for them with several $20 bills. The change she recived back was less than $10. How much change did she receive?
40 dollars and n= 6 would get her 4 dollars back IF two 20s is considered 'several'
60 wont work 80 100 120 140 160 180 won't work but:
$200 - n^2
200 - 14^2 = 4 dollars is the the next one I find that would work.....
