Please complete this assignment using the Simply Scheme mode of
DrScheme.
The assignment may be done alone or in pairs using the
ideas in the Pair

You cannot pair up with the
same person more than once during the semester.
For each function, be sure to follow the new design
recipe (incorporating Conditional Functions) that was given
in class on Thursday 11/30.
If you are defining auxiliary functions, you need to show the 6
steps of the Design Recipe for each of the auxiliary functions, as well as
the 6 steps of the Design Recipe for the main (or primary) function.

If you do not fully understand any of the directions above or the
questions below, please e-mail
me as soon as possible.
Programs
1) At Exit 17, the speed limit on the Southern State Parkway is 55 mph.
Develop a function named radar which takes someone's speed in mph and
returns one of the following sentences: '(under limit), '(at limit), or
'(over limit), based on that person's speed.
2) Develop the function describe-temp, which consumes a Fahrenheit
temperature and returns 'Warm if the temperature is 80 or
greater, 'Mild if the temperature is between 60 and 80 (including
60),
and 'Cold if the temperature is below 60.
3) Exercise 4.4.2a in How to
Design Programs. (Develop the
function tax, which consumes the
gross pay and produces the amount of tax owed. For a gross pay of
$240 or less, the tax is 0%; for over $240 and $480 or less, the
tax rate is 15%; and for any pay over $480, the tax rate is 28%.)
4) EXTRA CREDIT: Exercise 5.1.5 in How to Design Programs. In the
