1.) The school's florist has to order roses and carnations for Valentine's Day. Roses cost the florist $20 per dozen and carnations cost $5 per dozen. The profit on roses is $20 per dozen and on carnations it is $8 per dozen. The florist
can spend at most $450 on flowers and must order at least 20 dozen carnations, but the florist can order no more
than 60 dozen flowers. How many of each flower gives the florist the greatest profit?
