Ginny knits two different capes. The ‘Ginny’ model requires 3 hours of knitting and 7  hours to embellish the cape. The ‘Helen’ model requires 5 hours to knit and 5 hours to embellish the cape. Ginny has at most 60 hours a month to knit the capes and at most 100 hours a month to embellish the capes. How many capes should she make to  maximize her profit if she makes a profit of $80 on each ‘Ginny’ cape and a profit of  $100 on each ‘Helen’
