The manager of a theater knows that 900 tickets were sold for a
certain performance. If orchestra tickets sold for $3 each and balcony
tickets for $2 each, and if the total receipts were $2300, how may of
each kind of ticket were sold?
On a Christmas package Audrey needs to use only 40-cent stamps and
