Question

A jeweler orders necklaces from a website that offers $6 shipping for any-size order. Each necklace costs $7. The jeweler wants to know the total cost of ordering n necklaces. What is the independent (input) variable?

Answer 1

The independent variable is the number of necklaces ordered (n), and the dependent variable is the total cost of ordering the necklaces (y).

Step-by-step explanation:

The independent variable in this scenario is the number of necklaces ordered, which is represented by the variable n. The dependent variable is the total cost of ordering the necklaces. To determine the total cost, we multiply the number of necklaces (n) by the cost per necklace ($7) and add the fixed shipping cost ($6). Therefore, the equation that represents the total cost (y) in terms of the number of necklaces (n) is:

y = 7n + 6
