First solve the following specific problems, then write an algorithm in pseudocode for general problems of the same type. Be sure your pseudocode is clear, consistent, and properly indented.
The algorithm should allow for changes in the $10 price and for purchases under 20 units. The algorithm should allow for changes in the 50 cents reduced rate.
The algorithm should allow for changes in the height of the cylindrical tank and the diameter of the bottom.
If the initial odometer reading was 40,550 and the second reading was 40,800, how many miles did you travel between fills ? If it took 10 gallons of gas to fill the tank, what was your mileage in miles per gallon ?
The algorithm should allow for changes in the first and second odometer readings and the number of gallons needed to fill the tank.
The algorithm should allow for changes in the length, width, and height of the box.
The Eureka Water Company charges the homeowner one of the following fees:
| Cubic Feet of Water Used | Fee |
|---|---|
| usage < 1000 | $15 Flat rate |
| 1000 <= usage < 2000 | $.0175 per cubic foot |
| 2000 <= usage < 3000 | $.02 per cubic foot |
| usage >= 3000 | $70 Flat rate |
Your Algorithm should allow the customer to purchase any amount of water.
Your Algorithm should allow the user to input different rates for the:
- lower than 1000 cubic feet purchase
- 1000 to 2000 cubic feet purchase
- 2000 to 3000 cubic feet purchase
- over 3000 cubic feet purchase
Your Algorithm should allow Mr. Rodin to keep any number of firecrackers for himself. The user should be allowed to specify any number of children. The user should be allowed to specify any number of firecrackers per child.
Sample input/output for your program is listed below. Your program's output is in bold. Sample numbers entered by the user are given. There is no specific solution for this problem.
Please input an integer, 0 to end: 6
Please input an integer, 0 to end: 19
Please input an integer, 0 to end: -4
Please input an integer, 0 to end: 0
The largest integer entered was 19.
Answer to Problem: ____________ gallons.
The algorithm should obtain the length, height, and width of the room from the user. Note that your answer should be in whole gallons of paint.
The algorithm should allow for changes in the number of hours worked and the hourly rate.
