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?
If the price per pack increases by $8, the number of packs sold per day decreases by 1.
If the price per pack increases by $4, then number of packs sold per day decrease by 1.
If the price per pack increases by $1, the number of packs sold per day decreases by 4.
If the price per pack increases by $1, the number of packs sold per day decreases by 8.

The table shows the amount in Yang’s saving account at the end of each month. Select all the equations that could represent the change in Yang’s savings account.
𝑦 − 1145 = 45(1 - 𝑥)
𝑦 + 650 = −90(𝑥 − 12)
𝑦 + 325 = −45(𝑥 + 12)
𝑦 − 650 = −45(𝑥 − 12)
𝑦 − 325 = 90(𝑥 − 12)

The members of the Drama Club sold their old costumes in a booth at the school craft fair. Their profit was the difference between the amount of money they made selling the costumes and the cost of the booth. The cost of the booth was $50 and each of the costumes was sold for the same price. After the members of the Drama Club has sold 9 costumes, they made a profit of $62.50. The function 𝒑 represents the Drama Club's profit as a function of 𝒄, the number of costumes they sold. What does the 𝒄-intercept of the function represent?
The 𝒄-intercept represents a profit of $0 when 4 costumes are sold.
The 𝒄-intercept represents a profit of $12.50 when 5 costumes are sold.
The 𝒄-intercept represents a profit of $50 when no costumes are sold.
The 𝒄-intercept represents a profit of $37.50 when 1 costume are sold.
