Price tags: the answers
Four questions, each with one true number. Here they are with their answers, how to reason each one out, and where the number comes from. Play today's Price tags.

- NRF and Prosper Insights & Analytics
The answer: about $3.1 billion. Flowers trailed jewelry ($7 billion), an evening out ($6.3 billion) and clothing ($3.5 billion).
Napkin math - 40Mhouseholds buying flowers (about 1 in 3)
- ×$60a bouquet
≈$2.4B
The answer comes to about $3.1 billion (National Retail Federation). To reason it out, take 40 million households buying flowers (about 1 in 3), times $60 a bouquet, and you get about $2.4 billion. The estimate is 1.3 times too low, close enough to score 8.9 out of 10. Any guess from $1.6 billion to $6.2 billion scores 7.0 or better, because the game only counts how many times off you are.

2. A year of Golden Gate tolls: About 17 million drivers paid the Golden Gate Bridge's southbound toll in the year to June 2026. How much toll money did the bridge collect that year?
- Who pays
- Only southbound drivers, heading into San Francisco
The answer: about $170 million. Northbound drivers cross free, so about 34 million vehicles used the bridge that year but only half of them paid.
Napkin math - 17Mdrivers paying the toll
- ×$10a crossing
≈$170M
The true figure is about $170 million (Golden Gate Bridge, Highway and Transportation District). On a napkin, take 17 million drivers paying the toll, times $10 a crossing, and you get about $170 million. That is almost exactly the real number, and a guess like it scores 10.0 out of 10. The target is wider than it looks: every guess between $85 million and $340 million scores at least 7.0.

- 215 performances

- Radio City Music Hall, New York
The answer: about $191 million. Over 1.2 million tickets were sold for the 2025 holiday season, the show's highest attendance in 25 years.
Napkin math - 200shows
- ×6,000seats at Radio City
- ×$150a ticket
≈$180M
The true figure is about $191 million (Madison Square Garden Entertainment). On a napkin, take 200 shows, times 6,000 seats at Radio City, times $150 a ticket, and you get about $180 million. It's 1.1 times too low, which as a guess would still have scored 9.7 out of 10. Because only the ratio counts, anything between $95 million and $380 million was worth 7.0 or more.
4. A family's water for a year: According to the EPA, about how much does the average American family spend on water in a year?
- Each person uses
- About 82 gallons a day at home
The answer: more than $1,000. The EPA says WaterSense fixtures and Energy Star appliances can cut more than $380 a year off that.
Napkin math - 12months a year
- ×$80on each water bill
≈$960
The true figure is more than $1,000 (US Environmental Protection Agency, as of 2024). Without looking anything up, take 12 months a year, times $80 on each water bill, and you get about $960. That is almost exactly the real number, and a guess like it scores 9.8 out of 10. The target is wider than it looks: every guess between $500 and $2,000 scores at least 7.0.
