Al's and Barbara's produce stands are illustrations of proportional relationships
- The unit rate at Al’s Produce Stand is 0.25, and the unit rate at Barbara’s Produce Stand is 0.24
- The equation at Al’s Produce Stand is y = 0.25x, and the equation at Barbara’s Produce Stand is y = 0.24x
Step 1: The constant of proportionality
From the question, we have the following ordered pairs
- Al’s Produce Stand: (x, y) = (6,1.50)
- Barbara’s Produce Stand: (x, y) = (13,3.12)
The unit rate is calculated as:
[tex]k = \frac yx[/tex]
So, we have:
Al
[tex]k = \frac{1.50}{6}[/tex]
[tex]k = 0.25[/tex]
Barbara
[tex]k = \frac{3.12}{13}[/tex]
[tex]k = 0.24[/tex]
Hence, the unit rate at Al’s Produce Stand is 0.25, and the unit rate at Barbara’s Produce Stand is 0.24
Step 2: The equation
This is represented as
[tex]y = kx[/tex]
So, we have:
Al
[tex]y = 0.25x[/tex]
Barbara
[tex]y = 0.24x[/tex]
Hence, the equation at Al’s Produce Stand is y = 0.25x, and the equation at Barbara’s Produce Stand is y = 0.24x
Step 3: The missing values
This cannot be determined, as the table is not properly formatted
