Question

The high school jazz band is selling homemade leather bracelets at a local craft fair to raise money for a trip. The group spent $200 on supplies, which is enough to make 260 bracelets. The group is charging $2 per bracelet at the craft fair. Suppose b is the number of bracelets sold, and f(b) is the profit the band makes on the sales. What are the independent and dependent variables in this situation?

Answer 1

f(b) is the dependent variable since it relies on selling the bands to earn profit while B doesn't rely on anything

Hope this helps!

Answer 2

b is independent, f(b) is dependent

Explanation:

To see which variable is independent/dependent, it is the matter of "which one relies on the other"? Here, it would make sense that the profit is dependent on the sales, because the more you sell, the more you make, and not the more you make, the more you sell (in this situation). The variable that relies on the other (the profits, or f(b)) is the dependent variable, and the one that does not (the number of bracelets sold) is the independent variable.
