Spring Garden Planning
Today I started to plan my garden. The rectangular garden where I am going to plant is three feet longer than it is wide.
One third of the garden area will be sunflowers.
Another quarter will be planted with brow-eyed susans.
Only a fifth of my garden will contain columbine.
A sixth of my garden will be filled with trillium.
The rest will be foxgloves.

Capture the Flag!
The Algebra and Geometry classes at Mathland Hgh School are planning to play a game of Capture the Flag in the woods behind the school. They’ve been discussing how to fairly divide the woods into two territories.
They’ve drawn a map of the woods and added a coordinate plane. The Algebra class will put their base at (-8, 15). The Geometry class will put their base at (4, -3).

Choosing Charity
In the wake of the recent tsunami, a company decided to donate to a disaster relief fund. The company started by pledging a certain amount of money.
To encourage their 60 employees to make individual contributions, the company pledge to also donate an additional fixed amount for each employee who made a personal donation to the fund.
The company treasurer determined that if one-third of the employees chose to make a donation, the company’s part of the total donation would be $7000. If 50% of the employees donated, the company’s part of the total donation would be $7750.
