Suzie wants to sell her painted coasters at the farmer’s market. She has to pay a fee to set up her booth and she spends a certain amount of money on the materials needed to create each coaster. If the cost of selling s coasters is given by c = 25 + 1.40s, then the value 1.40 best represents

• the fee for setting up her booth

• the price at which she sells a coaster

• the cost of materials needed to make a coaster

• the number of coasters she plans to sell per hour

Grandma Barb is taking a typing class. Before beginning the class, she could type 32 words per minute. Each day she attends the class, she improves this speed by 7 words per minute. Write an equation that gives Grandma Barb’s typing speed, S, in words per minute, after d days of class.

• S = 32 + 7d

• S = 32d + 7

• S = 7d - 32

• S = 32 - 7d

What is the equation of the line in standard form?

• 3x - 2y = 12

• 5x - 6y = 12

• -4x + 2y = 12

• -8x - 2y = 12

Tickets to see a movie on a weekday are $7.50 and tickets to see a movie on a weekend are $10.00. Cale has $80 saved up to spend at the movies over summer break. Let x be the number of weekday movies Cale can see and y be the number of weekend movies Cale can see. Which of the following linear equations correctly relates x and y?

• 7.50x + 10.00y = 80

• -7.50x + 10.00y = 80

• 7.50x - 10.00y = 80

• -7.50x - 10.00y = 80

Suppose the average price of 1 pound of bananas was $0.63 in 2022 and is expected to go up by 5 cents every 2 years. The average price of 1 pound of oranges was $1.40 in 2022 and is expected to go up by 4 cents a year. If each fruit’s average price is plotted on an xy-coordinate plane with years since 2022 on the horizontal axis and average price in dollars per pound on the vertical axis, which graph would have a steeper slope?

• The graph for oranges would have a steeper slope.

• The graph for bananas would have a steeper slope.

• Both graphs would have the same slope.

• Neither graph would have a slope.
