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.

  1. 1. A week at Shake Shack: How much did an average company-run Shake Shack sell in a week in 2025?

    Counts
    Company-run Shacks

    The answer: about $76,000. Shake Shack's average weekly sales were flat in 2025, as higher menu prices offset fewer guests.

    Napkin math
    1. 400customers a day
    2. ×$20each
    3. ×7days a week

    ≈$56k

    The answer comes to about $76,000 (Shake Shack Inc.). On a napkin, take 400 customers a day, times $20 each, times 7 days a week, and you get about $56,000. The estimate is 1.4 times too low, close enough to score 8.7 out of 10. Any guess from $38,000 to $150,000 scores 7.0 or better, because the game only counts how many times off you are.

    Jewelry

    The answer: about $29.1 billion. It beat 2025's record of $27.5 billion, and gifts for romantic partners made up $14.5 billion of it.

    Napkin math
    1. 165Mpeople who celebrate (about half of us)
    2. ×$150each on gifts and a night out

    ≈$24.8B

    The answer comes to about $29.1 billion (National Retail Federation). To reason it out, take 165 million people who celebrate (about half of us), times $150 each on gifts and a night out, and you get about $25 billion. That comes out 1.2 times too low, and a guess that far off still scores 9.3 out of 10. Because only the ratio counts, anything between $15 billion and $58 billion was worth 7.0 or more.

  3. 3. A week at Texas Roadhouse: How much did one company-run Texas Roadhouse take in during an average week in 2025?

    Counts
    Dine-in and to-go
    Open
    Dinner every day, lunch on weekends at most

    The answer: about $162,000. About $22,000 of an average Texas Roadhouse's weekly sales in 2025 were to-go orders.

    Napkin math
    1. 800guests a day
    2. ×$25a meal each
    3. ×7days a week

    ≈$140k

    The answer comes to about $162,000 (Texas Roadhouse, Inc.). On a napkin, take 800 guests a day, times $25 a meal each, times 7 days a week, and you get about $140,000. It's 1.2 times too low, which as a guess would still have scored 9.4 out of 10. Because only the ratio counts, anything between $81,000 and $320,000 was worth 7.0 or more.

    Move your car for the street sweeper, on the days the sign says

    The answer: about $119 million. Street cleaning was the city's most common parking ticket, second only to school-zone speed cameras among all violations.

    Napkin math
    1. 1.8Mtickets written
    2. ×$65a ticket

    ≈$117M

    The answer comes to about $119 million (New York City Department of Finance). Without looking anything up, take 1.8 million tickets written, times $65 a ticket, and you get about $120 million. That is almost exactly the real number, and a guess like it scores 9.9 out of 10. The target is wider than it looks: every guess between $59 million and $240 million scores at least 7.0.
