School Fair Planning
Your school is organizing an annual fair with games, food, and activities. You need to help plan the fair by combining knowledge from all your math topics: fractions for recipes, decimals for money, algebra for planning, geometry for layout, and data analysis for success measurement.
Use fractions to scale recipes and decimals for pricing
Apply geometry for booth placement and area calculations
Use data analysis to predict attendance and profits
You're planning a pizza booth. The original recipe makes 8 slices, but you need to make 120 slices. Each slice costs $0.75 to make and sells for $2.50. The booth space is a 6 ft × 8 ft rectangle. Calculate the profit per square foot of booth space.
Scale the recipe from 8 slices to 120 slices.
Scale factor = 120 ÷ 8 = 15
You need to make 15 times the original recipe
Calculate total cost and revenue using decimal operations.
Total cost = 120 slices × $0.75 = $90.00
Total revenue = 120 slices × $2.50 = $300.00
Profit = $300.00 - $90.00 = $210.00
Find the area of the booth space.
Booth area = 6 ft × 8 ft = 48 square feet
Divide total profit by booth area.
Profit per sq ft = $210.00 ÷ 48 sq ft = $4.375 per sq ft
The pizza booth generates $4.38 per square foot of profit.
You need to arrange game booths in a 20 ft × 30 ft area. Each booth is 4 ft × 6 ft. You want to leave 2 ft walkways between booths and around the edges. If each booth charges $3.00 per game and averages 25 games per hour, what's the hourly revenue per square foot of the entire area?
Find how much space is available for booths after accounting for walkways.
Total area = 20 ft × 30 ft = 600 sq ft
Walkway area = 2 ft around all edges = 2 × (20 + 30) × 2 = 200 sq ft
Available for booths = 600 - 200 = 400 sq ft
Determine how many booths can fit in the available space.
Booth area = 4 ft × 6 ft = 24 sq ft
Number of booths = 400 sq ft ÷ 24 sq ft = 16.67
Maximum booths = 16 (can't have partial booths)
Find the total hourly revenue from all booths.
Revenue per booth per hour = 25 games × $3.00 = $75.00
Total hourly revenue = 16 booths × $75.00 = $1,200.00
Calculate revenue per square foot of the entire area.
Revenue per sq ft = $1,200.00 ÷ 600 sq ft = $2.00 per sq ft
The game booth area generates $2.00 per square foot per hour.
Based on past data, 60% of the school's 400 students attend the fair. Of those who attend, 3/4 buy food, 1/2 play games, and 1/3 buy souvenirs. If food averages $8.50 per person, games average $5.00 per person, and souvenirs average $12.00 per person, what's the total expected revenue?
Find how many students will attend the fair.
Attendance = 400 students × 0.60 = 240 students
Find how many students participate in each activity.
Food buyers = 240 × 3/4 = 180 students
Game players = 240 × 1/2 = 120 students
Souvenir buyers = 240 × 1/3 = 80 students
Calculate revenue from each activity category.
Food revenue = 180 × $8.50 = $1,530.00
Game revenue = 120 × $5.00 = $600.00
Souvenir revenue = 80 × $12.00 = $960.00
Add up all revenue sources.
Total revenue = $1,530.00 + $600.00 + $960.00 = $3,090.00
The expected total revenue for the school fair is $3,090.00.
An art class is making a mural. The design is 3/4 the size of the wall (12 ft × 8 ft). Each student can paint 2.5 square feet per hour. If 15 students work for 3 hours, what fraction of the mural will be completed?
A science class is growing plants. Each plant needs 1/3 cup of water daily. The class has 24 plants and a 2-gallon water container. If 1 gallon = 16 cups, how many days will the water last? What percentage of the container is used per day?
A basketball tournament has 8 teams. Each game lasts 1.5 hours, and there are 2 courts. If each team plays every other team once, how many total games are there? If the tournament runs for 6 hours per day, how many days will it take?
