   Marlo Island, an invented country used to practice real ideas (cards A to D). Card A, from the Marlo Statistics Office, a table of last year's export income (total $500 million): coffee beans 72 percent, fish 18 percent, fruit 10 percent. Card B, from the same office: last year a bag of coffee sold for $200; this year it sells for $140, and Marlo's farms sold the same number of bags both years. Card C, from the Marlo Coffee Growers' Association press release: "Coffee is the heart of Marlo. Prices always come back, so no change is needed." Card D, from the Statistics Office: Marlo makes almost no fuel or machines and buys them from other countries with its export income. Fish and fruit exports stayed at last year's amounts.

2. 1.

   From card A, how much of Marlo's export income came from coffee beans last year, Ari asks?

   • $140 million, the price of a bag of coffee this year
   • $180 million, found by taking half of the $360 million total
   • $72 million, since the table shows the number 72
   • $360 million, found by taking 72 percent of $500 million
3. 2.

   Last year's $360 million of coffee was sold at $200 a bag. The same bags sold this year at $140. How much less coffee income did Marlo earn, Bo asks?

   • $180 million less, since the price fell by about half
   • $60 million less, since the price fell $60 a bag
   • $108 million less, since 1.8 million bags each sold for $60 less
   • $252 million less, since that is this year's coffee income
4. 3.

   Fish and fruit exports stayed the same. By about what percent did Marlo's total export income fall, Esme asks?

   • About 28 percent, found by dividing $108 million by this year's $392 million
   • About 22 percent, since $108 million is about 22 percent of $500 million
   • About 72 percent, the share of income that came from coffee
   • About 30 percent, the same as the fall in the coffee price
5. 4.

   Card D says Marlo buys fuel and machines with its export income. Which chain follows from cards B and D, Jun asks?

   • A lower coffee price makes Marlo grow more coffee, which fixes the import problem
   • A lower coffee price also cuts the prices of fish and fruit, so the other exports earn less
   • Buying fewer imports lowers the coffee price, so export income falls
   • A lower price cuts export income, so Marlo can buy fewer imports
6. 5.

   Card B shows the coffee price falling while fish and fruit exports stay the same. How might a coffee farmer and a fisher on Marlo see it, Milo asks?

   • Both lose the same share, since both sell their goods on Marlo
   • The fisher loses more, since fish is a larger share of the island's catch
   • The farmer is hurt by the lower price; the fisher may not be
   • Neither is affected, since the same number of bags were sold
7. 6.

   Suppose Marlo doubles its fruit exports and the other exports stay the same. Coffee is $360 million and the new total is $550 million. About what share is coffee now, Noah asks?

   • About 50 percent, since doubling one export splits income in half
   • About 65 percent, still the largest share but lower than before
   • About 72 percent, since coffee income did not change
   • About 79 percent, since adding fruit makes coffee more important
8. 7.

   Card C says prices always come back. Does card B support that, Pia asks?

   • Yes: a $140 price shows the price is already coming back
   • No: card B shows one price fall and nothing about what comes next
   • No: a Statistics Office report cannot be used as evidence
   • Yes: farms sold the same bags, so prices must rise again
9. 8.

   A student says, "Coffee plants regrow, so Marlo's coffee income is safe." Which reply is best, Ren asks?

   • Right: renewable crops keep a steady price
   • Wrong: coffee is not renewable, because farmers must replant it
   • Not safe: coffee is renewable, but its price can still fall
   • Right: resources that run out can lose value, but crops cannot
10. 9.

    Which source would best check card B's coffee price, Tala asks?

    • Another statement from the growers' association, since it speaks for farmers
    • A record of coffee sale prices at the island's export port
    • A tourist guide that describes coffee farms on the island
    • A newspaper article retelling the price from the press release
11. 10.

    At this year's $140 price, about how many bags would Marlo need to sell to earn last year's $360 million, and how does that compare with the 1.8 million sold, Zee asks?

    • About 2.6 million bags, about 0.8 million more than last year
    • 2.6 million more bags than last year
    • 1.8 million bags, the same as last year
    • About 1.3 million bags, since a lower price means fewer bags
