Question

Judah made bracelets to sell at his school’s craft bazaar. He made seven dollars for each bracelet that he sold. Write a function rule to define the total amount y Judah made based on how many bracelets x he sold. Give an example of how the function rule works. Which is the dependent variable? The independent variable?

Answer 1

y = 7x
Example:
He sold 10 bracelet, so x = 10.
y = 7(10) = 70.
So, he made $70.
y is the dependent variable because it changes as x changes whereas x is the independent variable because it doesn't depend on anything
