-Multiple Choices Algorithm ​- by Mark Kelly+You might think it's too hard to re-do your own yard, but that's not really true. If you have an idea about what you want your yard to look like, you can learn how to landscape it to match your vision. Just read this article to learn some tips for landscaping and you'll be all set.[[http://​www.picowiki.com/​pagolo11/​index.php/​How%20To%20Incorporate%20Multiple%20Plants%20In%20A%20Great%20Landscape%20Design|Soft Play Floor Tiles]]

The unit cost of the stuff varies according ​to the quantity ordered. Customers can order any number ​of items.  Stuff Pty Ltd use this scale: +When you are planning landscaping for your yard, make sure to use plants, and flowers well suited for the climate you live in. Check the zone rating ​of plants, and make sure they will do well in your area. Investing in shrubs and trees, and have them die is discouraging,​ and also expensive.

-10-19 items = $97 each +
-20-29 items = $92 each +
-30-39 items = $88 each +
-40-49 items = $85 each +
-50 or more = $82 each+
  
-Task: using pseudocode, create an algorithm ​to calculate the unit cost of the items at different quantities. Then calculate ​a total cost with 10% GST added.   +Plan before you start shopping. It's important ​to know what you're getting yourself into. Before you go shopping for the things you need, make a plan for yourself. Determine exactly what you're doing, what the costs will be, and the skill level involved. It would be unwise ​to just start landscaping without some sort of plan. You could easily end up wasting a great deal of time, and money.

-An electrical company is developing a new main-powered sensorlight with the following requirements:​ +
- +
-• It turns on its LED light for a predetermined time (e.g. 60 seconds) after sensing movement with its passive infrared (PIR) detector. +
- +
-• It does not turn the light on if its light detector senses that the room is already well illuminated (e.g. during the day) +
- +
-• While its light is on, any further movement detection resets the timer back to its starting value and the countdown starts again. +
- +
-Convert your algorithm into a working simulation ​of the light. ​ You will need to simulate: +
- +
-• The day/night sensor (e.g. with radio buttons) +
- +
-• The movement sensor (e.g. with a mouse click or keypress) +
- +
-• The LED light (e.g. with a shape changing its colour) +
- +
-Show the value of the countdown ​time onscreen to verify its behaviour. +

 +Take a bit of time to research the right types of plants to use in your landscaping design. You can go to your local nursery or big-box home-improvement store and ask them questions about the plants they sell. Always keep in mind the growing requirements in your own yard when considering which plants to use.
  
 +When planning a landscaping project for your house, you need to know in what amounts of materials are sold and how much you'll need. This is important because you might not be able to visualize your project in cubic yards and do not want to risk buying too little or too much.
  
 +Buy lumber for outdoor projects during the winter months. It is going to be cheaper than during the spring and summer months. You may also be able to find some really great deals on trees, soil, shrubs and other things by purchasing them off season while demand is low as well.

If so, then you have learned something from this article. Keep in mind that there is more to know about landscaping,​ so do a little more research about the subject. When you think you're ready get to landscaping and improve the look of your home.
