1. You are on time if it is a school day an dtime is less than 800. You are also on time if it is not a school day, no matter what time it is.

    on-time? : number (time) boolean(school-day?) -> boolean
   

2. An egg is “hard” if cooked 10 minutes or more, “raw” if cooked less than 6 min, and “soft” if it is cooked 6-10 min.

    egg-cook: number(minutes) -> string
   

3. A deluxe burger costs $8 plus $3 each patty, and $2.25 extra if you want bacon. Write the function and two checks - one with bacon and one without.

    burger-cost: number(patties) boolean(bacon?) -> nubmer
   

4. A concert costs $75 for basic “300” level seating, $125 for “200” level seating, $190 for “100” level seating, and $250 for “floor”. There are a limited number of backstage passes available for an extra $200.

    concert-cost: string(seating) boolean(backstage?) -> number
   

   The basic version of this function only works with the strings mentioned in the problem. An advanced version of this function also works with other numbers is the 100-399 range, like this:

    (check-expect (concert-cost "230" false) 125)
   

5. This draw function has three options.

    ;; q5 : number -> image
   

   Options:

   1. Number 1-2: draw pic:bloch
   2. Number 3-4: draw pic:hacker
   3. Number 5 or more: draw pic:hieroglyphics scaled by n-3.

6. Make a picture of a burger according to the description below.

    pic-food: number(burgers) boolean(cheese?) boolean(tomato?) -> image
   

   There is a always a bun on the top and bottom (you can use a tan rectangle), then tomato, cheese, and burger patties. Each burger patty is 15 pixels high and 100 wide. Make the others look good (maybe a height of 5 for the cheese and 10 for the bun).

   An example of (pic-food 1 true true) is shown below.

   

7. A simple counting game.

   • the model is a number
   • draw handler: draw the number as black text inside a black outline circle
   • tick handler: the number goes up by 5 every 0.3 seconds
   • losing: If the number is between 500 and 1000, you lose and the number shows in red.
   • winning: If the number is above 1000 you win and the number minus 1000 shows in green.
   • key handler: hit “w” to win
