Rashida's Earnings and Equations

The video tutorial explains how Rashida models the earnings of her Snack Shack using a linear equation. It starts by defining the problem, identifying key variables, and initial conditions. The tutorial then guides through constructing the equation based on the given data and evaluates different answer choices to find the correct one. The final equation is 1.25x + 12 = 42, representing the earnings from selling potato chips.

What is Rashida trying to model with her equation?

• The cost of each bag of chips

• The total earnings of her Snack Shack

• The total number of customers

• The number of bags sold

What does the variable X represent in Rashida's equation?

• The number of bags sold

• The price of a bag of chips

• The starting amount of money

• The total earnings

How much does Rashida earn from selling one bag of chips?

• $25

• $42

• $12

• $1.25

What was Rashida's starting amount before selling any chips?

• $42

• $25

• $12

• $1.25

What was Rashida's total amount at the end of the day?

• $1.25

• $12

• $42

• $25

How do you represent the total earnings from selling X bags of chips?

• X / 1.25

• 1.25 * X

• 1.25 + X

• X + 1.25

Which of the following is the correct equation for Rashida's earnings?

• 1.25x + 42 = 12

• 12x + 1.25 = 42

• 1.25x + 12 = 42

• 1.25x - 12 = 42

Why is the equation 12x + 1.25 = 42 incorrect?

• The equation should equal 12

• The equation should equal 1.25

• The 1.25 should be subtracted

• The 12 is incorrectly placed

Why is the equation 1.25x - 12 = 42 incorrect?

• The 1.25 should be added

• The equation should equal 1.25

• The equation should equal 12

• Rashida started with $12, not negative $12

Why is the equation 1.25x + 42 = 12 incorrect?

• 42 is the ending amount, not the starting amount

• The equation should equal 1.25

• The 1.25 should be subtracted

• The equation should equal 42
