Build a CheckSplitter class

checksplitter.rb

# Build a CheckSplitter class.

# New CheckSplitter objects should have an attribute that stores the total cost of the meal.
#   They should have a way to define the tip amount (and a value that's set by default).
#   They should be able to define how many people are in the group.
#   They should use that information to help determine how much each person owes.

class CheckSplitter
  def initialize(meal, quality, group)
    @meal = meal
    @group = group
    @quality = quality
  end

  def find_tip                                          # 15% of bill for adequate service; 20% for great service;
    if @quality == "poor"                               # no less than 10% for poor service
      10
    elsif @quality == "adequate"
      15
    elsif @quality == "great"
      20
    else
      @quality = "poor"
      return 10
    end
  end

  def tip_amount                                        # find tip amount buy multiplying the meal cost by the tip
    @meal * (find_tip/100.0)                            # percentage based on the quality
  end

  def total                                             # finds the sum of tip amount and meal cost
    tip_amount + @meal
  end

    print "The meal is $#{sprintf("%0.2f", @meal)}. "
    puts  "There are #{@group} people in our group. "
    puts  "The services was #{@quality}, so the tip should be #{find_tip}% of the meal. "
    print "The total tip is $#{sprintf("%0.2f", tip_amount)}. "
    puts  "Each person owes $#{sprintf("%0.2f", split)}. "
    puts "-" * 60

print "How much was the cost of your group's meal? "
meal = gets.chomp.to_f
print "Was your service great, adequate, or poor? "
quality = gets.chomp.to_s
print "How many people were in your group? "
group = gets.chomp.to_i

checksplitter = CheckSplitter.new(meal, quality.downcase, group)
checksplitter.find_tip
checksplitter.tip_amount
checksplitter.total
checksplitter.split
checksplitter.describe_transaction
 

I changed it to make sure the user knows their options for the value of tip. Thanks for your input everyone! 😀
