Sue earns $6 an hour walking her neighbor's dog.
Part A: Create two variables and determine which is dependent and which is independent for this situation. (4 points)
Part B: List three ordered pairs to show the values of the two variables. (3 points)
Part C: Write an equation to represent the relationship between the two variables. (3 points)
(A) The independent variable is time because it is something that can be controlled and changed by the person walking the dog.
(B) Three ordered pairs are (1, 6), (2, 12), (0.5, 3).
(C) The equation is:
Money earned = 6t
What is an expression?In mathematics, an expression is a combination of numbers, variables, and operations that are grouped together to represent a mathematical statement.
Part A:
In this situation, the two variables are:
Independent variable: Time (in hours) spent walking the dog
Dependent variable: Amount of money earned (in dollars)
The independent variable is time because it is something that can be controlled and changed by the person walking the dog. The dependent variable is the amount of money earned because it is directly affected by the amount of time spent walking the dog.
Part B:
Here are three possible ordered pairs to show the values of the two variables:
(1, 6) - Sue earns $6 for walking the dog for 1 hour.
(2, 12) - Sue earns $12 for walking the dog for 2 hours.
(0.5, 3) - Sue earns $3 for walking the dog for half an hour (30 minutes).
Part C:
The relationship between the two variables can be represented by the equation:
Money earned = Hourly rate x Time spent walking
In this case, the hourly rate is $6 and the time spent walking is represented by the variable "t". Therefore, the equation is:
Money earned = 6t
where "t" is the time (in hours) spent walking the dog and "6t" is the amount of money (in dollars) earned for that time.

A manager samples the receipts of every fifth person who goes through the line. Out of 50 people, 4 had a mispriced item. If 1,400 people go to this store each day, how many people would you expect to have a mispriced item?
Answer:
112 people
Step-by-step explanation:
[tex]\frac{4}{50}[/tex] = [tex]\frac{x}{1400}[/tex] write the proportion where x is the number of people with a missplaced time
50x = 5600 cross multipy
x = 112 divide both sides by 50
