Section 1.12 Unit 1 Projects

90 minutes

These projects were designed by Leigh Anne Fitz of Virginia Beach City Public Schools and the autograding tests were designed by Kate McDonnell of Cherry Creek Schools in Colorado.

Subsection 1.12.1 Project 1: Road Trip Budget Planner

A family is planning a road trip and wants to estimate fuel costs, food costs, and see if they qualify for a random travel discount. You will write code to plan their road trip budget.

Program Requirements: Ask the user for the following information and store the input into variables.

Driver’s name
Total trip miles
Vehicle miles per gallon
Gas price per gallon
Number of travelers
Food budget per person

Calculate the following and store the results into variables:

Gallons of gas needed
Fuel cost
Total food cost
Total trip cost
Average cost per traveler
Whole number of gas stops (assume there will be a stop every 120 miles)
Remaining miles after the last full gas stop
Random discount between 5% and 20% (divide by 100 to convert to decimal)
Discounted total

Display a formatted trip summary (see sample below).

Sample output:
---------------------------------
ROAD TRIP SUMMARY
—------------------------------
Driver: Maria
Number of Travelers: 4
Gas Needed: 30.18 gallons
Fuel Cost: $108.35
Food Cost: $220.00
Total Cost: $328.35
Average Cost Per Traveler: $82.09
Random Discount: 14%
Discounted Cost: $282.38
Estimated Gas Stops: 8
Miles After Last Stop: 45

Project 1.12.1.

Calculate a road trip budget from the inputs of driver name, total trip miles, vehicle miles per gallon, gas price per gallon, number of travelers, and food budget per person. Calculate the gallons of gas needed, fuel cost, total food cost, total trip cost, average cost per traveler, whole number of gas stops, remaining miles after the last full gas stop, random discount, and discounted total. Display a formatted trip summary like below. Please use the variables provided in the starting code below. Run your code at least once with the following input for autograding:

Sample input: Pat, 200, 30, 4.00, 3, 15
---------------------------------
ROAD TRIP SUMMARY
---------------------------------
Driver: Pat
Number of Travelers: 3
Gas Needed: 6.67 gallons
Fuel Cost: $26.67
Food Cost: $45.00
Total Cost: $71.67
Average Cost Per Traveler: $23.89
Random Discount: 13%
Discounted Cost: $62.35
Estimated Gas Stops: 1
Miles After Last Stop: 80.00
