Based on last week's sales, a store manager concluded that by pricing the store's pack of 12 donuts at $8, the store will sell about 80 packs per day. Raising the price to $8.50 per pack of 12 donuts will cause sales to fall to about 76 packs per day. If a linear model based on this data is used to predict the daily sales of y packs of when the price per pack is x dollars, which statement is true about the slope of this linear model? A. If the price per pack increases by $8, the number of packs sold per day decreases by 1. B. If the price per pack increases by $4, then number of packs sold per day decrease by 1. C. If the price per pack increases by $1, the number of packs sold per day decreases by 4. D. If the price per pack increases by $1, the number of packs sold per day decreases by 8.

Based on last week's sales, a store manager concluded that by pricing the store's pack of 12 donuts at 38, the store will sell about 80 packs per day. Raising the price to $8.50 per pack of 12 donuts will cause sales to fall to about 76 packs per day. If a linear model based on this data is used to predict the daily sales of y packs of when the price per pack is x dollars, which statement is true about the slope of this linear model? A. If the price per pack increases by $8, the number of packs sold per day decreases by 1. B. If the price per pack increases by $4, then number of packs sold per day decrease by 1. C. If the price per pack increases by $1, the number of packs sold per day decreases by 4. D. If the price per pack increases by $1, the number of packs sold per day decreases by 8. 18.
