Understanding Linear Functions in Sales

The video tutorial explains Cameron's weekly salary as a linear function of vacuums sold. It covers the slope and vertical intercept, their meanings, and graphical representations. The tutorial also demonstrates how to evaluate the function for specific sales and solve for the number of vacuums needed to achieve a target salary.

What is the base salary Cameron earns even if he sells no vacuums?

• $120

• $400

• $840

• $1,200

How is the slope of the salary function best described?

• The salary remains constant regardless of sales

• The salary increases by $120 per vacuum sold

• The salary increases by $400 per vacuum sold

• The salary decreases by $120 per vacuum sold

What does the slope of 120 represent in Cameron's salary function?

• Cameron earns $120 for every 10 vacuums sold

• Cameron earns $120 for every 5 vacuums sold

• Cameron earns $120 for every vacuum sold

• Cameron earns $120 for every 100 vacuums sold

If Cameron sells 10 vacuums, by how much does his salary increase?

• $2,000

• $1,200

• $400

• $120

What is the vertical intercept of the salary function graph?

• (400, 0)

• (0, 400)

• (120, 0)

• (0, 120)

What does the vertical intercept indicate about Cameron's salary?

• He earns $120 if he sells no vacuums

• He earns $400 only if he sells vacuums

• He earns $0 if he sells no vacuums

• He earns $400 even if he sells no vacuums

How much does Cameron earn if he sells 37 vacuums?

• $3,840

• $4,840

• $5,000

• $4,400

What is the value of V when Cameron's weekly salary is $8,560?

• 60 vacuums

• 70 vacuums

• 68 vacuums

• 65 vacuums

If Cameron wants to earn $8,560 in a week, how many vacuums must he sell?

• 60

• 65

• 70

• 68

What is the equation used to find the number of vacuums Cameron needs to sell to earn a specific salary?

• s(V) = 400 + 120V

• s(V) = 120V - 400

• s(V) = 120 + 400V

• s(V) = 400V + 120
