I am having a hard time understanding this problem. Could you help me set the equation up and find the solution? It seems quit simple but i'm not getting it.
Bernice withdrew $985 in $5 and $20 bills from her savings account.If she had 65 bills altogether, how many of each amount did she have?
Thank you for your time,
Mrs. Gibson

You can put this solution on YOUR website!
Let f= the number of $5 bills she withdrew
Let t= the number of $20 bills she withdrew
f+%2B+t+=+65
t+=+65+-+f
5f+%2B+20t+=+985
5f+%2B+20%2865+-+f%29+=+985
5f+%2B+1300+-+20f+=+985
-15f+=+-1300+%2B+985
-15f+=+-315
f+=+21
t+=+65+-+f
t+=+44
She withdrew 21 $5 bills and 44 $20 bills
check:
5f+%2B+20t+=+985
5%2A21+%2B+20%2A44+=+985
105+%2B+880+=+985
985+=+985
OK
