Information and IdeasHardComparing shares across two totals
Information and Ideas practice question
Loaves sold on one Saturday:
Bakery X: 120 sourdough, 40 rye
Bakery Y: 90 sourdough, 75 rye
A food writer claims that rye makes up a larger share of Bakery Y's loaves than of Bakery X's. Which choice most effectively uses data from the table to support the claim?
- A. Rye is 75 of Bakery Y's 165 loaves, about 45%, but only 40 of Bakery X's 160 loaves, 25%.Correct
- B. Bakery X sold more sourdough loaves than Bakery Y did.
- C. Bakery Y sold 75 rye loaves.
- D. Both bakeries sold more sourdough than rye.
Answer: A. Rye is 75 of Bakery Y's 165 loaves, about 45%, but only 40 of Bakery X's 160 loaves, 25%.
The claim is about shares, so the support must compute rye as a fraction of each bakery's total — choice A does, and the shares differ as claimed.
Why the other answers are wrong
- B. Bakery X sold more sourdough loaves than Bakery Y did.
- Sourdough counts don't establish rye's share.
- C. Bakery Y sold 75 rye loaves.
- A count without a total is not a share.
- D. Both bakeries sold more sourdough than rye.
- True of both, but it doesn't compare the rye shares.
