Here are the notes from today:




Systems of inequalities for your homework problems:
#23. x = yellow cake, y = strawberry cake
because we can't have negative cakes, x >= 0, y >= 0
2 hours for yellow and 3 hours for strawberry: 2x + 3y <= 450
Revenue: 25x + 35y

#25. x = play houses, y = sheds
we can't have negative houses/sheds, so x >= 0 and y >= 0
2.5x + 2y <= 20
x + y <= 45
