# Recall in problem 2.4.5 you wrote some code that calculated
# the amount of money in an account based on this formula:
#
#   amount = principal * e ^ (rate * time)
#
# Those three variables are given above again, as well as a
# fourth: goal. We want to see if the investment given by
# these values will exceed the goal. If it will, we want to
# print this message:
#
#  "You'll exceed your goal by [extra money]"
#
# If it will not, we want to print this message:
#
#  "You'll fall short of your goal by [needed money]"
#
# If the investor will meet their goal, [extra money] should
# be the final amount minus the goal. If the investor will
# not meet their goal, [needed money] will be the goal minus
# the final amount.
#
# To make the output more legible, though, we want to round
# the difference to two decimal places. If the difference is
# contained in a variable called 'difference', then we can
# do this to round it: rounded_diff = round(difference, 2)
#
# Working with new and unfamiliar functions or abilities is
# part of learning to code, so use this function in your
# answer!

#
# For example, for the initial values above, your calculator
# would print:

# 4 * 7 = 28

# division to avoid worrying about rounding errors.`

# Diamonds are typically evaluated according to four aspects:
# - Cut: The way the diamond is cut
# - Clarity: How clear or flawless the diamond is, rated
#   as F (the best), IF, VVS, VS, SI, or I (the worst)
# - Color: How colorless the diamond is, rated from "D" (the
#   best) to "Z" (the worst)
# - Carat: How large the diamond is, weighed in carats
#
# Cut is usually a matter of personal preference. Clarity,
# color, and carat are matters of value: the clearer, more
# colorless, and larger a diamond is, the greater its value.
#
# Imagine you're shopping for a diamond. You have your
# preferred cuts, and you have a budget in mind. You're shown
# a diamond whose characteristics are represented by the cut,
# color, clarity, and carat variables above. You'll buy the
# diamond if its cost is less than your budget, and if its
# cut is one of your preferred cuts.
#
# At this store, every diamond has a base cost of 100.
#
# For every color rating worse than "D", the cost decreases by
# 2%. An "F" color diamond would be worth 0.96 * the diamond
# cost otherwise because "F" is two colors worse than "D".
#
# A diamond's value is doubled for every level of clarity above
# I. A "VVS"-clarity diamond is worth 8 * the diamond cost
# otherwise because "VVS" is three levels higher than I, and
# doubling its value three times raises its value by 8x total.
#
# After finding its price based on color and clarity, its price
# is multiplied by its weight in carats.
#
# Your program should print "I'll take it!" if you will buy the
# diamond, "No thanks" if you will not. To purchase it, its price
# must be less than your budget and its cut must be one of your
# preferred cuts.

# characters by using the ord() function. ord("E") - ord("D")
# is 1; ord("Z") - ord("D") is 22.

# - Everyone pays $20.
# - If you purchased your car before 2013 (in 2012 or earlier),

# - If the car is electric, you pay an additional $200 fee.
#   (This is real.)
# - To renew, you must have passed an annual emissions check,
#   unless your car is electric, or if you're 65 or over and
#   the car's age is 10 years or older.
#
# Your code should print one of two messages. If the person
# needs to pass an emissions test in order to renew their tag,
# it should print, "You must pass an emissions test first."
# This would be the message to print if emissions_passed is
# False and if they are not eligible for either exemption
# mentioned above.
#
# If the person is eligible to renew their tag, the code should
# print: "Your renewal fee is $__.", where __ is the renewal
# cost. Round the renewal fee to the nearest integer. This will
# be $20, plus $200 if the car is electric, plus 1% of car_value

# In Bryan Cranston's autobiography, he describes how after
# his success on Breaking Bad, he developed a scoring system
# for evaluating new scripts that he received.
#
# First, he would assign the script a grade -- A, B, C, D, or
# F -- in each of five categories: Story, Text, Role, Director,
# and Cast.
#
# Then, he would tally those grades into a total score for the
# script, according to the following chart:
#
#            A   B   C   D   F
# Story     +6  +5  +4  +2  +0
# Text      +5  +4  +3  +1  +0
# Role      +4  +3  +2  +1  +0
# Director  +3  +2  +1  +0  +0
# Cast/Misc +2  +1  +0  +0  +0
#
# For example: an A story, B text, C role, D directory, and
# F cast would get a score of 12: +6 for the story, +4 for the
# text, +2 for the role, +0 for the director, and +0 for the
# cast.
#
# Then, based on that score, the script would be assigned a
# category (note these are slightly different from the image
# because we've excluded the time variable):
#
# 20: Perfect score
# 17 to 19: Must do
# 14 to 16: Seriously consider
# 12 to 13: On the bubble
# 11 or below: Pass
#
# The variables above give the letter grades assigned to each
# of the five components. Write a program that calculates the
# total score he would assign to the script represented by
# these variables. Then on the next line, print the category
# he would assign to that script. For example, for the values
# above, this program would print:
#
# 12
# On the bubble
#
