Florida's third- through 12th-graders are busy taking the annual FCAT exam this week. So we thought perhaps you'd like to see if you could pass, too. Here are three sample questions from a 10th-grade (exit level) math FCAT. Do you know the answers?

1) A wholesaler is offering two different package deals of roses and carnations to florists. One package contains 20 dozen roses and 34 dozen carnations for $504.00. The other package contains 15 dozen roses and 17 dozen carnations for $327.00. This information can be represented by the system of equations below, where r represents the cost of one dozen roses and c represents the cost of one dozen carnations. 

20r + 34c = 504
15r + 17c = 327

What is the cost, in dollars, of one dozen roses?

2) An electrician charges a $45 fee to make a house call plus an hourly rate for labor. If the electrician works at one house for 3 hours and charges $145.50 for the job, what is the electrician’s hourly rate?

3) Kendra has a compost box that has the shape of a cube. She wants to increase the size of the box by extending every edge of the box by half of its original length. After the box is increased in size, which of the following statements is true?

F - The volume of the new compost box is exactly 112.5% of the volume of the original box.
G - The volume of the new compost box is exactly 150% of the volume of the original box.
H - The volume of the new compost box is exactly 337.5% of the volume of the original box.
I - The volume of the new compost box is exactly 450% of the volume of the original box.

[Answers from the answer book: 1 - $15, 2 - $33.50, 3 - H; for the record, the Gradebook calculated question #2 and came up with $35.17 .]
