In 1999, nearly all households in Country X purchased salty snacks. About 91% of households bought potato chips, purchasing an average of 9.8 pounds and spending roughly $26 over the year. A broader category—all chips (including potato, corn, and tortilla)—was purchased by 95.5% of households, with average annual purchases of 16.3 pounds. Other salty snacks, such as pretzels, cheese puffs, microwave popcorn, and packaged or bulk nuts, were purchased by 96.8% of households.
Considering all salty snacks, 99.2% of households made purchases in 1999. Among those who did, the average household bought 31.8 pounds and spent approximately $76.40. On a per-person basis, the average quantity purchased was 14.5 pounds.
Three key points emerge:
• Salty snack consumption was nearly universal, so almost all households would have been affected by a per-pound tax.
• Purchase quantities and spending varied systematically by household characteristics and demographics.
• Despite this variation, salty snacks represented a relatively small portion of household spending.

Official Solution:
In 1999, more households purchased potato chips than any other individual type of chip.
Not supported. While 91.3% of households purchased potato chips and 95.5% purchased all chips (including potato, corn, and tortilla), this does not mean potato chips were purchased by the largest percentage of households among individual chip types. Another type, such as corn chips, could have had a similar or higher purchase rate, and the overlap among types is unknown. No individual breakdown by chip type is provided.
Pretzels and microwave popcorn were less popular than potato chips in 1999.
Not supported. Pretzels and microwave popcorn are included in “other salty snacks,” purchased by 96.8% of households—more than the 91.3% for potato chips. However, since individual purchase rates for pretzels and popcorn are not given, we cannot compare their popularity directly with potato chips.
Pretzels and microwave popcorn were more popular than potato chips in 1999.
Also not supported. While “other salty snacks” overall were purchased by more households, we don’t have separate figures for pretzels or microwave popcorn. We cannot determine if either was individually more popular than potato chips.
There were approximately two people per household in 1999.
For all salty snacks, the average household purchased 31.81 pounds, and the per capita quantity was 14.47 pounds. Dividing gives about 2.2 people per household. Since 99.2% of households made purchases, it is reasonable to extrapolate this to the overall household population with high confidence. Supported.
Taxes on salty snacks were more popular than other food taxes in 1999.
Not supported. The material does not mention tax preferences, opinions, or comparisons to other taxes. “More popular” could imply greater public support or broader impact, but neither interpretation is supported by the text.
