• Highlight the code below & copy it.
• Paste it into Bitsbox.
• Run code. What does it do?
  • ​How much money do you raise by selling 4 cups of lemonade?
  • How much money do you raise by selling 50 cups of lemonade?
• Supplies cost $45/week. How will you need to update the answer equation to show only profit? Assuming price is still $1.25/cup:
  • ​How many cups of lemonade must you sell to break even? (In other words, how many cups of lemonade must you sell to offset the cost of supplies?)
  • What will your profit be if you sell 50 cups of lemonade?
  • The $45.00 in supplies allows you to make 135 cups of lemonade. What is your maximum profit this week?
  • How many cups do you have to sell per week to break even?
• Update code, so that it prompts user to input price.
  • How many cups do you need to sell to break even at $0.75/cup?
  • What price do you need to charge to earn a profit of at least $25?
• Try out a different fill & sound. 
• Try moving message around the screen. For example, for message =, the 100, 200 are x, y. The far left-hand corner of screen is 0, 0.
